	* itpp/itbase.h, itpp/base/mat.h, itpp/base/vec.h:
	Small changes to the documentation to allow the

	Modules section (helps new users)

2006-12-12  Conrad Sanderson  <conrad_s@users.sourceforge.net>

	* itpp/base/vec.h, itpp/base/vec.cpp: Added vector versions
	of elem_mult_inplace(), elem_mult_out(), elem_div_out(),
	elem_mult_sum() and elem_div_sum().
	See the 2006-12-07 entry by Conrad for more information.

2006-12-11  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/signal/transforms.cpp, itpp/signal/transforms.h: Minor

	resulted in different output samples of the IFFT fading generator
	on SPARC Solaris using GCC 3.4.5, than the ones obtained in other
	enviroments. The problem was probably caused by a different order
	of calculating the random arguments of the concat() function. Do
	not know if this is a bug of GCC for Solaris, or it is not fully
	specified behaviour in C/C++ standards.

2006-12-07  Conrad Sanderson  <conrad_s@users.sourceforge.net>

	* itpp/base/mat.h, itpp/base/mat.cpp: Added elem_mult_inplace(),
	elem_mult_out(), elem_div_out(), elem_mult_sum() and elem_div_sum().
	elem_mult_inplace() is a fast version of B = elem_mult(A,B).
	elem_mult_out() and elem_div_out(): element-wise multiplication
	and division of matrices, respectively, with the result stored
	in a matrix given as an argument.

	and division of matrices, followed by summation of the resultant

	* itpp/base/matfunc.h, itpp/base/matfunc.cpp: Added sumsum(),
	which is a fast version of sum(sum(A)) (i.e. calculates the
	total of all elements in a matrix).

	* itpp/stat/mog_diag.h: Fixed a small typo.

2006-12-06  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/modulator_nd.*: Minor code readability and
	efficiency improvements

2006-11-10  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/srccode/gmm.h: Fixed bug [1570388] by adding a warning
	message to `get_no_mixtures()' function saying that it is
	deprecated and that `get_no_gaussians()' should be used instead
	(merged rev. 713:714 from itpp-3-10 branch).

	* itpp/comm/channel.cpp: Fixed default initialisations and checks
	in particular fading related methods (set_no_frequencies(),
	set_filter_length(), etc.).
	(merged rev. 657:716 from the channel-update branch)

2006-11-09  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/channel.cpp: Removed wrong and unnecessary checks for
	positive time offsets.
	(merged rev. 657:716 from the channel-update branch)

2006-11-07  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/channel.h: Minor documentation changes.
	(merged rev. 657:716 from the channel-update branch)

	* itpp/comm/channel.cpp, itpp/comm/channel.h: The channel
	discretization function improved and moved to the TDL_Channel
	class. An additional parameter `sampling_time' is required when
	setting the channel profile using the Channel_Specification
	(merged rev. 657:716 from the channel-update branch)

	* itpp/comm/channel.cpp: Simplified GaussI and GaussII Doppler
	spectra calculations.
	(merged rev. 657:716 from the channel-update branch)

2006-11-06  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/channel.cpp, itpp/comm/channel.h: Improved interface
	for setting various fading parameters in Channel_Specification and
	TDL_Channel classes. Relative Doppler is set to 0.7 by default,
	when only relative power (Rice factors) is specified. BTW, the
	documentation was revised.
	(merged rev. 657:716 from the channel-update branch)

	* itpp/comm/channel.cpp, tests/channel_test.ref: Fixed a bug in
	LOS process generation in the Independent and Static fading
	(merged rev. 657:716 from the channel-update branch)

	* tests/channel_test.cpp, tests/channel_test.ref,
	itpp/comm/channel.cpp, itpp/comm/channel.h, tests/Makefile.am:
	Fading generators inheritance model redesigned. Now there are
	three types of fading: Independent, Static and Correlated. The
	Correlated fading can be generated using Rice (MEDS), FIR or IFFT
	methods. A basic test program of channel classes added.
	(merged rev. 657:716 from the channel-update branch)

2006-11-02  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/channel.cpp, itpp/comm/channel.h: A set of new
	features and improvements added:
	- `Rice' keyword removed from the DOPPLER_SPECTRUM enum; `Jakes'
	  or `Classic' should be used instead.
	- Explicit selection of a fading type implemented. When fading_type
	  is equal to `Correlated', non-zero normalised Doppler needs to be
	  specified. The default fading type is set to `Independent'.
	- Better implementation of independent fading generator.
	- Added missing initialisations of time_offset in FIR and IFFT
	  fading generators.
	- Removed the `decimation_factor' parameter, since its use was bad
	  in a few places.
	(merged rev. 657:716 from the channel-update branch)

	* itpp/comm/rec_syst_conv_code.cpp: To avoid code duplication, the
	local `com_logmap()' function replaced with its safer
	implementation `log_add()' from "itpp/base/logexpfunc.h". Thanks
	to Erik G. Larsson for pointing this out.

2006-11-01  Adam Piatyszek  <ediap@users.sourceforge.net>

	* AUTHORS, configure.ac, doc/local/authors.doc,
	itpp/base/logexpfunc.h, itpp/config_msvc.h: New `log_add()'
	function implemented, which calculates safely the following
	expression: log(exp(log_a) + exp(log_b)). Thanks to Conrad
	Sanderson for his patches.

2006-10-31  Adam Piatyszek  <ediap@users.sourceforge.net>

	* AUTHORS, doc/local/authors.doc: Developers Thomas Lemaire and
	Anders Persson retired.

	* doc/local/index.doc.in, doc/local/itpp_footer.html,
	doc/local/itpp_header.html: Main documentation page layout
	redesigned (should look better in higher resolutions).

	deprecated, because its name was a bit misleading (see bug
	[1480535]). Instead of it the following two functions were added:
	`int2bits()' and `levels2bits()'. The first one returns the number
	of beed required for representing an unsigned integer, e.g.
	"int2bits(0) = 1", "int2bits(2) = 2". The latter one returns the
	number of bits to code a certain, positive number of values
	(levels). For example: "levels2bits(1) = 1", "levels2bits(2) = 1".

	automake manual. Thanks to Ed Hill for reporting this bug and his
	work on RPM package for Fedora Core (merged rev. 676:677 from
	itpp-3-10 branch).

2006-10-14  Erik G. Larsson  <erik_g_larsson@sourceforge.net>

	* doc/tutorial/src/mimoconv.doc: Improvement to tutorial example

	* doc/local/installation.doc: Minor update

	* itpp/comm/modulator_nd.*, tests/modulator_nd_test.*: Fixed an
	error in ND_UQAM

2006-10-13  Erik G. Larsson  <erik_g_larsson@sourceforge.net>

	* doc/tutorial/src/mimoconv.doc: Update to reflect the change in
	LLR convention.

2006-10-12  Erik G. Larsson  <erik_g_larsson@sourceforge.net>

	* itpp/comm/llr.h, itpp/comm/modulator_nd.*: Changed the
	definition of LLRs from log(P(b=1)/P(b=0)) to log(P(b=0)/P(b=1))
	in the LLR and Modulator_ND classes. This was done to conform to
	the conventions in the scalar modulator class. (Note the interface

	* doc/tutorial/tutorial.doc, doc/tutorial/mimoconv.doc,
	doc/tutorial/src/mimoconv.cpp: Added first version of new MIMO

2006-10-08  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/modulator.h: Additional check added to prevent
	improper initialisation of symbols and bit2symbols in the
	Modulator class. This fix is related to bug [1572807].

2006-10-06  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/itassert.cpp, itpp/base/itassert.h: Implemented
	feature request [1569867]. Now, it_assert(), it_warning() and
	it_error() functions can use stream operators like `<<' or
	`std::endl' in a concatenation with strings, e.g.
	`it_error("Wrong value x = " << oct << x)'. Thanks to George
	Jongren for submitting a patch.

2006-09-18  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/channel.cpp: Removed redundant concat() functions in
	Gauss Doppler spectra's initialisation.
	(merged rev. 657:716 from the channel-update branch)

	* itpp/comm/channel.cpp, itpp/comm/channel.h: Implemented missing
	"Gauss I" and "Gauss II" Doppler spectra required by a few COST207
	channel models. These Gaussian spectra are only available in the
	Rice_Fading_Generator class
	(merged rev. 657:716 from the channel-update branch)

2006-09-05  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/channel.cpp, itpp/comm/channel.h: Added additional
	assertion checks for undersampled cases in Channel_Specification's
	discretize() function. It is now possible to discretize the
	channel with too low sampling frequency, but only if all taps
	except the first one use the default Jakes Doppler spectrum and
	has no LOS (Rice) parameters.
	(merged rev. 657:716 from the channel-update branch)

	* itpp/comm/channel.cpp, itpp/comm/channel.h: Fixed improper
	initialisation of los_power and los_dopp variables in TDL_Channel
	(merged rev. 657:716 from the channel-update branch)

2006-09-04  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/channel.cpp, itpp/comm/channel.h: Implemented
	exponential channel profile generation function. Cleaned up the
	interface of various fading generator classes:
	- only one generate() function with additional default parameter
	decimation_factor (instead of misleading name upsampling_factor)
	- implemented add_LOS() function in the base class, which is
	reused by the child classes
	- global jake_filter() function moved into FIR_Fading_Generator
	- all get_*() functions changed to the const ones
	- base class `init_flag' is now set in the initialisation list of
	the constructor.
	(merged rev. 657:716 from the channel-update branch)

2006-09-03  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/channel.cpp, itpp/comm/channel.h:
	Channel_Specification and TDL_Channel classes extended with
	support of LOS (Rice) fading for any tap. Doppler spectrum of type
	`Rice' is now merged with `Jakes' or `Classic', since the
	generation method is the same. To obtain `Rice' spectrum
	relative_power and relative_doppler needs to be defined for a
	certain tap(s).
	(merged rev. 657:716 from the channel-update branch)

2006-09-03  Erik G. Larsson  <erik_g_larsson@users.sourceforge.net>

	* doc/tutorial/matlab_itpp.doc: Expanded the Matlab/IT++
	conversion table.

2006-09-02  Erik G. Larsson  <erik_g_larsson@users.sourceforget.net>

	* itpp/comm/modulator.h, modulator_nd.h, modulator_nd.cpp:
	Documentation update and improvement of range checking in

2006-09-01  Adam Piatyszek  <ediap@users.sourceforge.net>

	* Makefile.am: Added new `snapshot', `snapshot-src' and
	`snapshot-html' targets for automatic creation of snapshot
	distribution packages.

2006-08-31  Tony Ottosson  <tonyottosson@users.sourceforge.net>

	* doc/tutorial/itfile.doc: Fixed small documentation bug.

2006-08-24  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/svec.h: Fixed bug [1545798]. Sparse vectors are now
	correctly compared using `==' operator. Thanks to Timo for
	reporting this bug.

2006-08-22  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/modulator.cpp, itpp/comm/modulator.h: Added simplified
	versions of demodulate_soft_bits() functions to the QPSK modulator
	class. This gave about 40% improvement in the demodulation

2006-08-21  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/modulator.h, tests/modulator_test.cpp: Added
	deprecated demodulate_soft_bits_approx() functions with a warning
	message for backward compatibility reasons. Besides, the default
	soft demodulation method of demodulate_soft_bits() functions is
	now log-MAP.

2006-08-19  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/channel.cpp: Fixed bug [1542064]. The problem was that
	the index in the tap_doppler_spectrum array in the
	TDL_Channel::init() function could go out of bounds, if the
	TDL_Channel class was used with two different channel profile
	lengths. Thanks to Jordy Potman for reporting this bug and
	providing a patch with a solution (merged rev. 645:646 from
	itpp-3-10 branch).

	* itpp/comm/modulator.cpp, itpp/comm/modulator.h,
	tests/modulator_test.cpp: Further redesign of 1D and 2D modulator
	classes. From now, there is only one templated base class
	Modulator, which can handle 1D (real) and 2D (complex)
	constellations. BPSK and PAM modulators are split into:
	BPSK_c/PAM_c classes which use complex valued interface but only
	real part of the signal is used, and BPSK/PAM classes that have
	real valued interface. Besides, demodulate_soft_bits() functions
	use additional parameter "method" to switch between Log-MAP or
	approximate demodulation algorithm.

	* itpp/base/elmatfunc.cpp, itpp/base/elmatfunc.h: Reverted the
	previous interface of binomial functions. "double binom()" defined
	for higher range of calculated results.

2006-08-19  Erik G. Larsson  <erik_g_larsson@users.sourceforge.net>

	* itpp/comm/egolay.cpp: Included "converters.h".

2006-08-19  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/egolay.cpp: Minor fix - "(int)floor()" replaced with

2006-08-18  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/elmatfunc.cpp, itpp/base/elmatfunc.h,
	itpp/base/itmisc.cpp, itpp/base/itmisc.h: Fixed bug [1542482]. Now
	binom(n, k) works properly. "double binom(int, int)" was
	redundant, because the result of this function was always
	integral. Therefore it was replaced with "int binom(int, int)".
	BTW, moved fact(), binom(), log_binom() and gcd() functions from
	itmisc.{cpp,h} to elmatfunc.{cpp,h}.

2006-08-16  Adam Piatyszek  <ediap@users.sourceforge.net>

	* tests/modulator_test.cpp, tests/modulator_test.ref: Updated
	tests of 1D and 2D modulators due to the recent redesign of these

	* doc/local/index.doc.in: Minor fix ("CVS" -> "SVN") (merged rev.
	633:634 from itpp-3-10 branch).

	* doc/doxygen_html.cfg.in: Include files and file list now contain
	a relative path.

	* itpp/comm/modulator.cpp, itpp/comm/modulator.h,
	tests/modulator_test.cpp, tests/modulator_test.ref,
	tests/pulse_shape_test.ref: Major redesign of one- and
	two-dimensional modulator classes. Modulator_2D is now a base
	class for QAM, PSK and PAM modulators. Moreover, QPSK and PSK
	inherits from the PSK class. Please note that input signal for
	Modulator_2D has now slightly different meaning. BTW, improper
	definition of QPSK constellation is fixed (it was in fact 4-QAM
	modulator previously).

	* itpp/comm/bch.cpp, itpp/comm/egolay.cpp: Added missing include

	* doc/doxygen_html.cfg.in, doc/local/itpp_header.html: Minor fixes
	in Doxygen config file.

2006-08-15  Adam Piatyszek  <ediap@users.sourceforge.net>

	tests/modulator_nd_test.ref, tests/llr_test.ref: Documentation
	updates and cosmetic changes.

2006-08-11  Adam Piatyszek  <ediap@users.sourceforge.net>

	* doc/local/verification.doc: Updated with Windows tests (merged
	rev. 612:613 from itpp-3-10 branch).

	* itpp/base/parser.cpp: Minor fix of uninitialised bool variable.

	* itpp/base/itmisc.h, itpp/base/random.h: Replaced deprecated
	hypot(x, y) function with std::sqrt(x*x + y*y) calculation. BTW,
	macro definition M_2PI replaced with a global constant m_2pi.

	* itpp/base/mat.cpp, itpp/base/mat.h: Fixed a minor problem of
	uninitialised matrix elements, when parsing values from a string

	* itpp/signal/sigfun.cpp: Fixed bug [1538210], caused by
	uninitialised variable `m2' used for covariance calculation.
	Thanks to Max Moorkamp for reporting this bug.

	* itpp/comm/modulator.cpp, itpp/comm/modulator.h,
	tests/modulator_test.ref: Further cosmetic changes and minor fixes
	in QPSK, PSK and QAM modulator classes. Use the new trunc_log()
	function when calculating log-likelihood ratio. Reference data for
	test program updated accordingly.

2006-08-10  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/modulator.cpp, itpp/comm/modulator.h: Minor fixes in
	BPSK and PAM modulator classes. Now use the new trunc_log()
	function when calculating log-likelihood ratio.

2006-08-10  Erik G. Larsson  <erik_g_larsson@users.sourceforge.net>

	* itpp/comm/rec_syst_conv_code.cpp: Now use the new trunc_exp()
	and trunc_log() functions instead of macros.

2006-08-10  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/modulator.cpp, itpp/comm/modulator.h: Modulator_1d and
	Modulator_2d classes revised with respect to bug [1456235]. The
	precision problems for high SNR have been solved by using the
	trunc_log() function recently defined in "logexpfunc.h" file.
	Thanks to Erik for his help in solving this problem. This fix
	closes the bug report [1456235].

	* itpp/base/logexpfunc.h: Added special truncated versions of
	log() and exp() functions, which might be used instead of the
	macros in modulator.cpp and rec_syst_conv_code.cpp (more stable
	and portable solution). These functions check if floating-point
	arithmetic is conforming to IEC 559 standard. If not, standard
	log()/exp() functions are used.

2006-08-09  Erik G. Larsson  <erik_g_larsson@users.sourceforge.net>

	* itpp/comm/rec_syst_conv_code.cpp: Changed functions into macros
	to handle truncation of argument of exp() and log().

	* itpp/comm/modulator.cpp, itpp/comm/modulator.h: Documentation
	updates and polishing of code.

2006-08-09  Adam Piatyszek  <ediap@users.sourceforge.net>

	* configure.ac, doc/Makefile.am, Makefile.am: Added `upload',
	`upload-src' and `upload-html' targets for automatic upload
	tarballs into SourceForge ftp server.

2006-08-08  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/parser.cpp: Fixed a minor bug in get<int>() function
	caused by too early execution of it_assert() check function.

	* itpp/base/mat.cpp, itpp/base/mat.h, itpp/base/vec.cpp: Fixed a
	minor bug in string parsing functions that prevented
	initialisation of a vector/matrix with an empty string "".

2006-08-08  Erik G. Larsson <erik_g_larsson@users.sourceforge.net>

	* itpp/comm/rec_syst_conv_code.cpp, itpp/comm/rec_syst_conv_code.h:
	Added floating point range tests when using exponential and
	logarithm functions to avoid numerical errors at high SNR in
	map_decode(), to address bug [1088420]. Updated documentation to
	suggest that the QLLR based decoders are used instead for maximum
	runtime efficiency and numerical stability.

2006-08-08  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/array.h, tests/array_test.cpp, tests/array_test.ref:
	Added new constructors and operator `=' which use string literals
	for Array initialisation. There is no need to use `set_array()'
	function any more. Test program improved as well. Source code of
	"array.h" beautified by the way.

	* tests/vec_test.cpp: Fixed improper file description.

	* tests/parser_test.cpp: Fixed minor compilation problem caused by
	passing C-style string as an argument of init(std::string)


2006-08-07  Adam Piatyszek  <ediap@users.sourceforge.net>

	itpp/protocol/tcp.cpp: Removed most of the "#pragma warning"
	statements needed by MSVC++ .NET compiler (merged rev. 577:578
	from itpp-3-10 branch).

	* win32/itpp.vcproj: Added _CRT_SECURE_NO_DEPRECATE and
	_CRT_NONSTDC_NO_DEPRECATE definitions that disable warnings on
	some deprecated C standard library and POSIX-compilant functions
	(merged rev. 577:578 from itpp-3-10 branch).

2006-08-04  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/parser.cpp, itpp/base/parser.h, tests/parser_test.cpp,
	tests/parser_test_data.txt: Added support for decimal, hexadecimal
	and octal notation in get_int() and get(int) parser functions.
	Also support added for "true" and "false" strings in get_bool()
	and get(bool) functions.

	* itpp/base/vec.cpp: Changed the way "a:b:c" format is parsed when
	(b = 0) and (a = c). Now it returns "a". Thanks to Erik for
	finding this bug (merged rev. 556:566 from a temporary sandbox

2006-08-03  Erik G. Larsson <erik_g_larsson@users.sourceforge.net>

	tests/rec_syst_conv_code_test.ref: Fixed a minor bug in the RSC
	code test program. The generator polynomials were initialised with
	a string using octal notation, which is not supported by Vec<>
	parser yet.

	* itpp/base/parser.cpp: Minor change in findname() function to
	adapt the parser to recent changes in Vec and Mat classes. Now
	fields in a temporary parsed string are separated with spaces
	instead of commas (merged rev. 556:566 from a temporary sandbox

	* tests/mat_test.cpp, tests/mat_test.ref, tests/vec_test.cpp,
	tests/vec_test.ref: Added vector and matrix initialisation tests
	with strings (merged rev. 556:566 from a temporary sandbox

2006-07-25  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/mat.cpp, itpp/base/mat.h, itpp/base/vec.cpp,
	itpp/base/vec.h (merged rev. 556:566 from a temporary sandbox

	New functions for initialising vectors and matrices from strings
	implemented. Main features of the improved parser are as follows:

	- Decimal, octal and hexadecimal notation support according to
	C/C++ conventions, i.e. octal number starts with `0' (e.g. `0133',
	`077'), decimal number starts with `1-9' or is a single `0' digit,
	hexadecimal number starts with `0x' or `0X' prefix and has at
	least one `0-9', `a-f'or `A-F' digit after (e.g. 0xFF, 0x0,
	0x070). Various representations can be mixed in one string.

	- Signed numbers supported, i.e. with `+', `-' or nothing in
	front, e.g. `-1000', `+0133', `-0x1'

	- Vector values can be separated with spaces ` ', tabs `\t' or
	comma `,', e.g. " -1 22, 47 0x5, 077"

	- Matlab's "a:b" or "a:b:c" notation for both increasing and
	decreasing values supported, e.g. "0:2:10", "-9:-18", "4:-1:0",

	- Matrix rows separated with a single semicolon `;'

	- Detection of syntax errors during parsing

2006-07-19  Adam Piatyszek  <ediap@users.sourceforge.net>

	* configure.ac, Makefile.am, itpp/Makefile.am, itpp/sources.mk,
	tests/Makefile.am, doc/local/installation.doc, INSTALL, TODO:
	Modularisation of the IT++ library implemented. It is now possible
	to skip the building of various modules using a set of
	`--disable-*' switches with the configure script. The
	documentation has been updated accordingly.

2006-06-15  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/convcode.h, itpp/comm/convcode.cpp: Fixed bug
	[1506524]. The `K' variable is now initialised in the

	BCH encoder/decoder class can be set to produce codewords in a
	systematic order. Thanks to Steve, aka "michboy", for providing
	patches and a simple test file.

2006-05-19  Adam Piatyszek  <ediap@users.sourceforge.net>

	* tests/timer_test.cpp: Minor fix to avoid a hazard in timing test.

	* configure.ac, itpp/base/binfile.cpp, itpp/config_msvc.h:
	Removed checks for <sys/stat.h>. Now using iostream based method
	for checking if a file exists.

	* itpp/srccode/audiofile.cpp, itpp/srccode/audiofile.h,
	Added templated read_endian and write_endian functions, which
	replaced the old macro based read/write ones. Finally removed
	`machdep.h', because endianness is now handled run-time.

2006-05-18  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/sources.mk, itpp/srccode/audiofile.cpp,
	itpp/srccode/machdep.h, itpp/srccode/sources.mk:
	Moved `machdep.h' into `itpp/srccode', since it is only included
	in `audiofile.cpp'. Cleaned up the `machdep.h' code, by the way.

	* itpp/base/binfile.cpp, itpp/base/binfile.h,
	itpp/base/itfile.cpp, itpp/base/itfile.h, itpp/base/itmisc.cpp,
	itpp/base/itmisc.h, itpp/itbase.h:
	Changed the method of detecting the endianness of a system -
	`itpp/base/machdep.h' is not used any more in the base module.

	* doc/local/verification.doc: Updated to reflect recent tests
	under Windows (MinGW with IT++ External).


2006-05-15  Adam Piatyszek  <ediap@users.sourceforge.net>

	asinh() and atanh() functions.

	* itpp/base/elmatfunc.cpp, itpp/base/elmatfunc.h: Finally fixed
	the declaration of `signgam' and definition and lgamma() function.
	This should solve problems on systems where lgamma() does not set
	`signgam' variable, e.g. under MinGW.

2006-05-11  Adam Piatyszek  <ediap@users.sourceforge.net>

	* tests/fix_test.cpp, tests/fix_test.ref, tests/llr_test.cpp,
	tests/llr_test.ref, tests/window_test.cpp, tests/window_test.ref:
	More "dirty" hacks added due to a floating-point rounding error
	under MinGW compiler.

	tests/window_test.cpp, tests/window_test.ref: Minor fixes in test
	programs due to different formatting under MinGW environment.

	* test/Makefile.am: Added a dirty hack using sed regular expresion
	that ensures floating point output in the form of `e-06' instead
	of `e-006', which is default for the MinGW compiler.

	* configure.ac: Check for a host added, which is used to disable
	building of a shared library on Windows based platforms.

2006-05-09  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/config_msvc.h: Manually updated the config header for
	MSVC++ .NET with MKL.

	* itpp/base/timing.cpp: Fixed gettimeofday() function definition
	for Windows based platforms (MinGW, MSVC++). No need for MINGW
	definition any more.

	* configure.ac, itpp/base/elmatfunc.cpp, itpp/base/elmatfunc.h:
	Added checks for `lgamma' and `tgamma' functions, and `signgam'
	declaration. This solves problems on some platforms where these
	declaration and/or functions are not available.

	* itpp/base/random.cpp: Added missing include file (undefined
	gamma function).

	* configure.ac, Makefile.am, tests/Makefile.am: Fixed a problem
	with different line endings on Windows based platforms. Now,
	sed program is necessary for performing tests.

2006-05-08  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/cblas.cpp: Fixed bug [1483125]. Now a complex dot
	product is properly returned by a dot function when using ACML
	blas libraries. Thanks to Danilo Zanatta for this bug report.

2006-05-04  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/itmex.h: Fixed missing std:: specifiers before complex<>

2006-05-03  Adam Piatyszek  <ediap@users.sourceforge.net>

	itpp/base/specmat.cpp, itpp/comm/channel.cpp,
	itpp/comm/modulator.cpp, itpp/signal/sigfun.cpp,
	itpp/signal/transforms.cpp, itpp/srccode/vq.h:
	Fixed bug [1480535]. Now needed_bits() returns a proper number of
	bits required to represent integer `n', e.g. "needed_bits(0) = 1",
	"needed_bits(7) = 3" and "needed_bits(8) = 4".

	* itpp/itmex.h: Fixed a small bug related to missing #include
	statement and cleaned up the code.

2006-05-02  Erik G. Larsson <erik_g_larsson@users.sourceforge.net>

	doc/local/sources.mk: Added AUTHORS page.

	* doc/local/help_wanted.doc: Cosmetic changes.

2006-04-27  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/galois.cpp: Added missing include file with log2()
	function declaration.

	* doc/sourceforge/howto_release_itpp.html: Updated due to CVS to
	SVN repository migration.

	* Redesign, separation and regrouping of some functions from the
	base module.

	The following changes have been applied:
	- Now using one overloaded and templated "apply_function" instead
	  of a set of various "vec_function" and "mat_function" in
	  "help_functions.*". Such a templated "apply_function", with the
	  same functionality, was implemented in "matfunc.*". Thus,
        - Moved trigonometric and hyperbolic functions (all inline, and
	  both ones for scalars and vectors) to a separate header file
        - Moved logarithmic and exponential functions to a separate header
	  file "logexpfunc.h".
        - Moved error functions to separate files "errorfunc.*".
        - Merged elementary mathematics functions from "scalfunc.*" with
	  the content of elmatfunct.*".	The rest of scalfunc.* content
	  moved to "itmisc.*". "scalfunc.*" removed.
        - A lot of minor changes that should improve the readability of
	  the base module.

2006-04-21  Adam Piatyszek  <ediap@users.sourceforge.net>

	* doc/local/index.doc.in, doc/local/itpp_header.html,
	/doc/local/itpp_footer.html: Added links to Feature Requests, IT++
	at freshmeat and Newcom project (logo).

2006-04-20  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/stat.h: Added Histogram class setup function provided
	by Jordy Potman. This closes Feature Request [1473059].

2006-04-13  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/signal/filter.cpp: Fixed bug [1469860]. Now fir1()
	declaration matches its definition. Thanks to Jordy Potman for
	reporting this bug.

2006-04-12  Adam Piatyszek  <ediap@users.sourceforge.net>

	* doc/doxygen_html.cfg.in: Doxygen configuration changed to

	of backslash functions using it_assert1() macro.

	* itpp/signal/filter.cpp, itpp/signal/filter.h: Fixed bug
	[1468011], so AR_Filter now works when using a single coefficient
	value, e.g. a = "0.5". Minor cosmetic changes applied by the way.

2006-04-10  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/comm/convcode.cpp, itpp/comm/convcode.h,
	tests/convcode_test.cpp, tests/convcode_test.ref: Fixed improper
	behaviour of the encode_trunc() and decode_trunc() functions. Now,
	each execution of these functions does not reset the encoder and
	decoder states, so it can be used to perform continous decoding
	process. An additional reset() function has been added to reset
	the encoder and decoder states.

2006-04-07  Adam Piatyszek  <ediap@users.sourceforge.net>

	* doc/local/verification.doc, doc/local/installation.doc: Minor
	documentation updates.

	functions provided by <cmath> under MSVC++ (different naming
	conventions). BTW, file headers updated.

	* itpp/itbase.h: Minor fix - including `itmisc.h' file.

2006-03-31  Adam Piatyszek  <ediap@users.sourceforge.net>

	* doc/local/verification.doc: Updated IT++ Supported Systems page
	with new tests.

	* config/acx_fft.m4: Improvements and fixes in external FFT
	library detection.

	checking for ACML's CBLAS library.

	* itpp/base/cblas.cpp, config/acx_cblas.m4, configure.ac,
	doc/doxygen_html.cfg.in, itpp/base/sources.mk: Fixed CBLAS
	interface when using ACML BLAS implementation. ACML C interface
	is not the same as in other implementation, so a limited set of
	wrapper functions has been created in `cblas.cpp' file.

2006-03-28  Adam Piatyszek  <ediap@users.sourceforge.net>

	* TODO: Updated to reflect recent changes.

	* itpp/base/itpp_version.cpp, itpp/base/itpp_version.h,
	itpp/itconfig.h, itpp/base/array.h, itpp/base/mat.h,
	itpp/base/newton_search.cpp, itpp/base/newton_search.h,
	itpp/base/sources.mk, itpp/base/vec.h, itpp/sources.mk: Merged the
	content of itpp/itconfig.h and itpp/base/itpp_version.{cpp,h}
	files into new files itpp/base/itmisc.{cpp,h}. The new files
	should include miscleaneous functions related to IT++ library.

2006-03-27  Adam Piatyszek  <ediap@users.sourceforge.net>

	* configure.ac, itpp-config.in: Minor fix in the itpp-config

	* doc/local/features.doc: Statistics classes and functions moved
	from signal-processing to base math module.

	* itpp/sources.mk: Added missing "itpp/itsignal.h" file.

	* itpp/srccode/lpcfunc.cpp, itpp/signal/fastica.cpp: Fixed
	improper include statements after moving signal-processing related
	classes and functions to a separate subdirectory.

	* config/acx_blas.m4: Removed unnecessary check for "libblas",
	beside "libf77blas" in ATLAS detection routines. This fixes a

2006-02-01  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/transforms.cpp: Fixed bug [1418707] by adding the
	FFTW_UNALIGNED option to the plan creation flags, which allows a
	standard memory allocation of input and output data. This
	temporary solution reduces performance on processors that use SSE
	and SSE2 instructions. (merged from itpp-3-9-branch)

	* configure.ac, NEWS: Updated for the next bug-fix release (merged
	from itpp-3-9-branch)

2006-01-31  Adam Piatyszek  <ediap@users.sourceforge.net>

	* configure.ac, config/*.m4, itpp-config.in, itpp.pc.in,
	doc/doxygen_html.cfg.in, itpp/config_msvc.h, itpp/base/*.{cpp,h},
	tests/*.cpp: Major redesign of the configuration scripts.

	The following things changed:
	- added support for ACML (AMD Core Math Library)
	- checks for BLAS now detect MKL, ACML, ATLAS and reference
	(from Netlib) BLAS implementations; if found, HAVE_BLAS is defined
	- checks for LAPACK also detect MKL, ACML, ATLAS and reference
	LAPACK library; if found, HAVE_LAPACK is defined
	- checks for CBLAS detect MKL, ATLAS and reference implementation,
	however	CBLAS is fully optional; if found, HAVE_CBLAS is defined
	- new checks for FFT: detects MKL or FFTW3 implementation; if
	found, HAVE_FFT and either HAVE_FFTW3 or HAVE_FFT_MKL8 are defined
	- new checks for <mkl_dfti.h> and <fftw3.h> header files provided
	by external libraries; not using <itpp/base/fftw3.h> any more.

	It is now possible to mix various implementation of BLAS, LAPACK
	and FFT routines, e.g.:
	- use MKL for BLAS, reference Netlib's LAPACK and FFTW3,
	- use ACML for BLAS and LAPACK, reference Netlib's CBLAS and

	This redesign has been tested using Cygwin and Gentoo Linux. The
	latter one had MKL v8.0.1, ACML v3.0.0, ATLAS v3.6.0, FFTW v3.0.1
	and Netlib's BLAS, CBLAS and LAPACK v3.0 libraries installed.

	TODO: Update installation instructions in the documentation. Test
	if the changes did not cause any problems for MSVC++ .NET users.
