File Release Notes and Changelog

Release Name: 4.0.6

Notes:
IT++ 4.0.6 is the next maintenance release based on the current IT++ stable
branch (itpp-4-0). As usual, a brief list of modifications and bug-fixes is
presented below:


Modifications:
--------------

* Added GDB debugger helper display macros for IT++ data types (feature
  request [1913404])

* Reduced number of divisions in a sinc() function implementation

* "itpp/config.h" no longer included in "itpp/base/itassert.h" header file


Bug-fixes:
----------

* Fixed broken implementation of toeplitz() function for the case when two
  different complex-valued input vectors are used as input arguments (bug
  report [2110119]).

* Fixed a minor bug in GF::set_size() method: the content of "alphapow" and
  "logalpha" static variables is now properly copied when resizing them.

* Fixed sort() and sort_index() so they again work for vectors with less
  than two elements.

* Fixed bug [2041474] in Vec<>::split() method, which was a regression with
  respect to the previous 3.10.x stable releases.

* Fixed incorrect usage of ZDOTU BLAS function when linking to 64-bit MKL
  library for GNU/Linux (zdotusub Fortran wrapper function is required)

* Suppressed warnings about deprecated "/Wp64" option when compiling with MS
  Visual C++ Express 2008

2008-10-05  Erik G. Larsson  <erik_g_larsson@users.sourceforge.net>

	* doc/local/verification.doc: Added Ubuntu 8.04 to list of tested
	systems

	* doc/local/installation.doc: Minor fix

2008-09-17  Adam Piatyszek  <ediap@users.sourceforge.net>

	* win32/itpp_acml.sln, win32/itpp_mkl.sln: Use CRLF line endings
	in MSVC++ solution files.

	* win32/itpp_acml_tests/itpp_acml_tests.sln,
	win32/itpp_acml_tests/specmat_test.vcproj,
	win32/itpp_mkl_tests/itpp_mkl_tests.sln,
	win32/itpp_mkl_tests/specmat_test.vcproj: Add MSVC++ project files
	for specmat_test.

2008-09-12  Adam Piatyszek  <ediap@users.sourceforge.net>

	* tests/Makefile.am, tests/specmat_test.cpp,
	tests/specmat_test.ref: Add specmat_test program for testing
	special vectors and matrices.

	Initially only toeplitz() function is tested.

	* itpp/base/specmat.cpp, itpp/base/specmat.h: Fix broken
	implementation of toeplitz() function.

	The previous implementation generated incorrect matrices for two
	complex-valued input vectors. This patch fixes this problem. BTW,
	the implementation is now based on a template function, so bmat,
	smat and imat matrices can now be generated.

	Thanks to Niklas Johansson for reporting this issue. This closes
	bug report [2110119].

2008-08-30  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/itassert.h: Get rid of config.h dependency from
	itassert.h header file.

	* itpp/comm/galois.cpp: Fix bug in GF::set_size() method, which
	was reported by Stephan Ludwig.

	Because "alphapow" and "logalpha" are static variables, every
	instantiation of the GF class uses the very same of them. If
	different instantiations of different Galois fields access this
	(e.g. 2^8 and 2^6, while 2^6 has been created first), the latter
	might overwrite/delete the log table of the previous while calling
	GF::set_size() method (2^8 widens the array to m+1=9, while not
	copying the 2^6 entries). The solution is to copy the contents of
	"alphapow" and "logalpha" when resizing them.

	Thanks to Stephan Ludwig for noticing this problem and also to
	EndZone for confirming it.

	* itpp/base/math/trig_hyp.h: Reduce number of divisions in a
	sinc() function.

	* itpp/base/sort.h: Make sort() and sort_index() work for vectors
	with less than two elements.

	Without this patch, the above two functions resulted in an
	assertion error. Thanks to Yngve Seln for reporting this problem.

2008-08-18  Erik G. Larsson  <erik_g_larsson@users.sourceforge.net>

	* extras/gdb_macros_for_itpp, extras/Makefile.am: Added GDB
	debugger display macros for IT++ data types.

	This closes feature request [1913404]. Thanks to Vasek Smidl for
	providing an initial version of the macros.

2008-08-11  Adam Piatyszek  <ediap@users.sourceforge.net>

	* win32/itpp_acml.vcproj, win32/itpp_acml_tests/*.vcproj,
	win32/itpp_mkl.vcproj, win32/itpp_mkl_tests/*.vcproj: Suppress
	warnings about deprecated "/Wp64" options in MSVC++ project files

2008-08-10  Adam Piatyszek  <ediap@users.sourceforge.net>

	* doc/tutorial/src/ldpc_bersim_awgn.cpp: Add missing "LL" suffix
	to 64-bit inteager initialisation

	This eventually fixes integer overflow error in LDPC BER
	simulation tutorial example.

2008-08-09  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/stat/mog_diag.h: Suppress a minor warning reported by
	Doxygen

	* doc/tutorial/src/ldpc_bersim_awgn.cpp: Fix minor problem with
	integer overflow in expression

	The initialisation of int64_t variable with a multiplied inteager
	constants caused an integer overflow of the temporary calculation
	result. This patch fixes this issue by using one big constant
	in the initialisation.

2008-08-07  Adam Piatyszek  <ediap@users.sourceforge.net>

	* itpp/base/vec.h, tests/vec_test.cpp, tests/vec_test.ref: Fix
	regression [2041474] in Vec<>::split() method

	In IT++ 3.10.x releases it was possible to split a vector at its
	end, e.g.:
	  vec v1 = "1 2 3 4 5";
	  vec v2 = v1.split(5);
	In the current stable branch (4.0.x) the above code results in an
	assertion. This patch fixes this regression and also improves the
	documentation, so it is clearly explained which elements are
	returned and which are stored in the original vector.

	Besides, the vec_test program now includes a new test for
	splitting a vector at pos = 0 and pos = datasize.

	Thanks to Yngve Selén for reporting this bug.

2008-08-02  Adam Piatyszek  <ediap@users.sourceforge.net>

	* m4/acx_blas.m4: MKL requires zdotusub Fortran wrapper function
	on x86_64 architecture

	This fixes broken blas_test and vector_test on 64-bit linux
	architectures when IT++ is linked to Intel MKL BLAS library. This
	fix is equivalent to passing "--with-zdotu=zdotusub" option to
	configure.
