Changes in 2.4.1.0 1. Fixed segfault occuring when calling solvers with (functions with no arguments) as arguments. 2. Fixed backward compatibility with gsl (e.g., robust linear fit was introduced recently, rlab can be linked to old versions of gsl). [PREVIOUS POSTS] Changes in 2.4.0.0 1. Thorough internal reorganization of solvers that call functions as arguments. A number of mini memory leaks have been resolved in the process. Certain invocation procedures modified so their execution is 10-20% faster. Haxes replaced by procedures uniform across different solvers. Changes in 2.3.3.8 1. Continuing work on cleaning/leaning/deglitching the code. Case in point: preventing existing functions to cause segmentation fault or return non-sensical results if their arguments were not correct. E.g., y = ifelse(x==[], 1, x[1]) used to fail if x is empty matrix because the function would assume that all three supplied arguments exist (here, x[1] does not exist if x is an empty matrix). E.g., polyval(x,a) treats properly any vector 'a', rather then just row vector. Previously, if 'a' was column vector it would go internally out of bounds, and return non-sensical result. Please note, in helping me eliminate such glitches I encourage you to send me nonsenses, or segfaults rlab creates while running your scripts. 3. More work on incorporating NaN's in rlab workings, e.g., see functions diff() or quot(). 4. Fixed functions writem() when operating on hdf5 file in append mode: it deletes previous value of the object before entering new one. Also writem("somefilename.h5", [], "/hdf/abs/object/name") will delete object "/hdf/abs/object/name" if argument is empty matrix. [PREVIOUS POSTS] Changes in 2.3.3.7 1. Continuing work on cleaning/leaning/deglitching the code. Changes in 2.3.3.6 1. Continuing work on cleaning/leaning/deglitching the code. 2. More work on patterns in function 'compact', set operations now work with string vectors as well. 3. sorting function has now three ways of dealing with nans: put them on top of the list, on bottom, or leave them in place. Changes in 2.3.3.5 1. Continuing work on cleaning/leaning/deglitching the code. 2. Some work on patterns is implemented in the function 'match' 3. Added operation with sets, some functionality with tables. All can tolerate nans. Changes in 2.3.3.4 1. Fixed corrupted 'y.tab.h' file in 2.3.3.3. 2. Continuing work on cleaning/leaning/deglitching the code. Changes in 2.3.3.3 Changes in 2.3.3.2 1. Continuing work on cleaning/leaning/deglitching the code. 2. Modified build script so that flex and bison can be used through 'make scanner'. Updated default rlab parser to output of flex 2.5.37. Changes in 2.3.3.1 1. Continuing work on cleaning/leaning/deglitching the code. Changes in 2.3.3.0 1. Consolidated rlab complex codes. 2. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code: case in point harminv and time-frequency toolbox. Changes in 2.3.2.3 1. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code. 2. Fixed build script: It can recognize libngspice on 32-bit systems. It builds the .bin. version without any addons with pgplot for plotting - see ./rconfigure_low32 in source root directory. Changes in 2.3.2.2 1. Added suggested build script for Raspberry Pi, "rconfigure_rpi." Rlab tested and operational on Raspberry Pi running opensuse 13.1. Binary version available, as well. Fixed different "#define" statements so that the same sources can be built on either of three architectures, armv6l, x86 & x86_64. 2. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code. Changes in 2.3.2.1 1. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code: emphasis on date time funcions. Changes in 2.3.2.0 1. New internal type: dense matrix, existing dense matrix formats converted to dense matrix type. 2. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code. Statistical functions improved so to ignore nan's. 3. Improved plplot interface: it now accepts lists for plotting 3-d lines and surfaces (plsplot) "mesh" style or "3d" style, and contours (plcont). Improved interna efficiency of data transfer to plplot. 4. Pattern recognition functions added: classify, cluster, distance matrix, localabsmaxi, localrelmaxi. Changes in 2.3.1.8 1. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code. 2. Updated configure script so to handle properly ImageMagick and gphoto2 library configurations. User still has to request the feature during configuring. Changes in 2.3.1.7 1. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code, e.g., prompt, or 'ans'. Changes in 2.3.1.6 1. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code. Silent upgrades completed. Changes in 2.3.1.5 1. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code. Changes in 2.3.1.4 1. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code. 2. Deglitched extraction of rlabplus-addons, so that scaled down version of rlab+rlabplus compiles even on old 32-bit machines (currently oldest machine that runs rlab is a toshiba laptop 1GHz, 512MB RAM, with suse 11.1 on it). Its configuration is given in script 'myconfigure_low32'. 3. Please note: All binaries available on the sourceforge are built using 'myconfigure_low32'. For all rlab+rlabplus features one has to build from sources. Changes in 2.3.1.3 1. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code: fixed some internal lack of features and overly optimistic dealing with non-existent variables. 2. Fixed omission in 'configure' script so that location of the jvm is properly passed to rlab start-up script. Same with some other libraries. 3. Finished filter. It works now for complex numbers as well. Changes in 2.3.1.2 1. Changes in configuration of rlab. I was hit by blast from the past: most of special-topic libraries added to rlab as a part of rlabplus are now optional, and need to be specified during 'configure' to be included. This was done so that rlab can be built on very old laptops running even older linuces (do you remember kde3.5?). What is still required are: hdf, gsl, curl shared library. On older systems arpack, glpk and superlu might be available as static libraries. Configure script takes that into account: One still needs to specify only the directory where the library resides, and hope that the headers are available through /usr/include. Overall, these are the latest flags needed to build rlab totally (see also 'myconfigure' script that lists them all): ./configure --with-jvm=[where is my JVM located? 'myconfigure' can find it for you] --with-ngspice=[where did I put shared ngspice when I built it? 'myconfigure' can try to find it] --with-arpack[=/dir/to/static or shared library, but only if different from default locations] --with-superlu[=/dir/to/static or shared library, but only if different from default locations] --with-im[=/dir/to/shared library, but only if different from default locations] --with-gphoto2[=/dir/to/shared library, but only if different from default locations] --with-plplot[=/dir/to/shared library, but only if different from default locations], or --with-pgplot, for the latter rlab contains its source tree - needed for old systems without plplot --enable-python[=/dir/to/shared library, but only if different from default locations] --with-suitesparse[=/dir/to/shared library, but only if different from default locations] --enable-glpk[=/dir/to/static or shared library, but only if different from default locations] Default behavior is not to install any. Even then, one gets system with bunch of improvements and new features, with many a bug or glitch fix. Changes in 2.3.1.1 1. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code: fixed some HDF bugs and glitches: 'isfile' works, reading and writing string matrices works. 2. Additional features to existing solvers, e.g. mean/var. Fixed filter function: it can now take the initial output as input parameter. Fixed 'eval' function: does not segfault if improper input. 3. Statistical lists <<val;wgt>> now support algabraic operations +, -, ./, .\, .*, and *. Some functions, e.g., mean,var, ..., support them from before. 4. Fixed glpk so it properly compiles on older version of the library (parameters have changed recently). 5. Fixed rgphoto in regards to nonexistent uint8_t type. 6. Rebuilt the plplot interface, as any further work on pgplot has been ceased (it blows on xinerama setup, creates windows that take half screen - 1 monitor). Most pgplot commands and structures should work under plplot: the two have almost identical functions. User now has to choose between --with-plplot and --with-pgplot flags when 'configure'-ing. 7. 'ans' variable stores the most recent result of command line calculations. Changes in 2.3.1.0 1. Fixed build-up script and rectified some omissions. 2. Added libgphoto2 through new command list 'gp'. If not wanted configure rlab with '--disable-gphoto2' 3. Added parts of ImageMagick through new command list 'image'. If not wanted configure rlab with '--disable-im' 4. Updated GLPK wrapper to work with versions of GLPK 4.52 and higher: Do I need to put this with --disable-glpk flag? 5. Cleaning/leaning/deglitching of the code. Minor fixes to some mathematic functions, e.g., mod. 6. If building from sources, there is a script 'myconfigure' which tries to figure out flags for compilation in regards to python, java, spice. Changes in 2.3.0.4 1. Fixed documentation omission. Flag for using java virtual machine should read --with-jvm=/dir/where/yourlibjvm.so.is and it should not contain the file name libjvm.so itself. Silly me. Also fixed some other glitches in configure script. 2. Cleaning/leaning/deglitching of the code. Modified output of diffevol solver and added convergence controls. Changes in 2.3.0.3 1. Notable new solver: a version of differential evolution algorithm is now available as solver 'diffevol'. 2. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code. Changes in 2.3.0.2 1. Build flags are better defined in configure script --disable-python (by default it is enabled, provides command list 'py') --with-jvm=/usr/lib64/libjvm.so (by default it is disabled, if enabled provides command list 'jvm') --with-ngspice (by default it is disabled, if enabled provides command list 'spice') 2. Added support for ngspice built as a shared library. 3. Updated to the latest version of the Boehm's Garbage Collector (gc-7.2). 4. Continuing work on adding more options to existing solvers, and cleaning/leaning/deglitching the code. Changes in 2.3.0.1 1. Removed static libraries arpack, amdpack, umfpack and superlu, and replaced them with the shared object ones available from your linux distribution - check install.txt. 2. Continuing work on: adding more options to existing solvers and functions, and cleaning/leaning/deglitching the code: fixed ngspice, added calendar library. 3. Add a calendar/date/time toolbox. Changes in 2.2.12.16 1. Added jvm set of functions that allow rlab to call java methods and passes parameters to them and get results from them. 2. Continuing work on: adding more options to existing solvers and functions, and cleaning/leaning/deglitching the code. Changes in 2.2.12.15 1. Added flag -e "cmds" so that commands can be executed when invoking rlab2 from the command line. The flag parameter "cmds" does not allow white spaces (feature of GNU getopt). 2. Fixed 'configure' script so that gcc version is correctly recognized. 3. Continuing work on: adding more options to existing solvers and functions, and cleaning/leaning/deglitching the code. Changes in 2.2.12.14 1. fixed build script - glpk was improperly removed. Changes in 2.2.12.13 1. libglpk removed from source. User needs to download the library and development files, and install them on his/her own. 2. Fixed wrong location of rlab headers in python.c.in 3. Fixed glitch in main.c that appears in newer versions of gcc, related to 'yydebug' Changes in 2.2.12.12 1. Fixed build script for python, so it builds properly on opensuse and fedora systems (thanks a.g.). 2. Continuing work on: adding more options to existing solvers and functions, and cleaning/leaning/debugging the code. 3. More functions, e.g., showkey, prompt, inputs. Changes in 2.2.12.11 1. Embedded python interpreter is now available. 2. Added some more options to existing solvers. 3. Continued work on removing bugs, and buglets, and code cleaning. Changes in 2.2.12.10 1. 'make flibs' now builds pgplot 2. fixed linking issues between 64 and 32-bit versions (each links to its respective /usr/lib{64} libraries). Fixed variable in 'configure' so that the system architecture is properly registered - should work on opensuse and redhat fedora systems. 3. continuous work on code cleaning and glitches removal. Changes in 2.2.12.8 1. Fixed the configure/Makefile so it properly links to libraries on fedora systems (and not just on opensuse32/64) [Thanks a.g.]. Fixed some of the testfiles. Clean-up/tidying the source code for some solvers that rely on fortran solvers (resolved segfaults that occur when fortran code is expected to write run-time messages). Fixed glitches in gsl solvers for minimization. Changes in 2.2.12.7 1. Functions fwrite/fseek/fread now work without glitches. 'fseek' requires file to be open prior to seeking it. Code now passes the script 'test.r'. Changes in 2.2.12.6 1. Fixed some memory leaks in read/write functions to the serial port. Added more options to the open-function. 2. Added some more solvers: harminterp. Modified some existing solvers: linterp and findroot. 3. Reviewed sections of the code. Fixed some small memory leaks. Changes in 2.2.12.5 1. Succesfully tested sockets on ethernet connected instruments - they have reached near-production quality. Same minor changes in some system functions: tic()/toc() now have a microsecond precision. Modifified/expanded some solvers, e.g., linterp. Changes in 2.2.12.4 1. configuration of rlab is changed. The script ./configure no longer checks for the presence of flex. Instead it uses the file provided with the distribution that was built with flex-2.5.35, and then fixed by hand. Added is option 'make scanner' that checks the file 'scanner.l' against local installation of flex and tries to compile the result. Such installation, however, has to be put in 'Makefile.in' by hand in line where '@FLEX@' is defined. 2. Added are few solvers, and some bugs and lack of features are corrected. 3. Sprannlib has been removed. Changes in 2.2.12.3 1. The directory 'examples' transferred to the rlab-test collection of files that user has to install in his/hers home directory, under ~/rlab/test. 2. More of the gsl: cumulative probability functions Changes in 2.2.12.2 1. Changes in internal handling of open HDF5 files that removed few remaining glitches in basic HDF5 handling functionality. The reliability is now at the production level for files containing rlab recognized data. 2. Added more options to some existing solvers, e.g., findmins. 3. More functions and operators are now matrix optimized (addition, subtraction, multiplication and division by element) 4. Added some gcc "#define"'s so that rlab builds properly on 32- and 64-bit architectures. Fixed install script (was for version 2.2.11). Changes in 2.2.12.1 Slight Modification of HDF5: 1. rlab scalar variables, i.e., matrices of size 1x1 are written as scalars (HDF5 data set of rank 0) rather then as matrices (HDF5 data set of rank 2, with dimensions 1 and 1). 2. When writing non-scalar vectors and matrices to HDF5 objects, an attribute "Transpose" with the value of unity is appended to them. This is to indicate to other software that is used to access the data that it needs to be transposed. If rlab reads a matrix that does not have that attribute with that value then it internally transposes it. 3. The format of writing (and reading) of the sparse real and complex matrices to a HDF5 file has changed to minimize recopying of the structure. An HDF5 storage of a sparse matrix is a compound of 7 variable length arrays (6 integer, 1 double, or double-double - complex, that is). Changes in 2.2.12.0 1. Read/write operations: (a) Limited access to HDF5 - can read and write all data types native to rlab, and can access atomic data sets within any HDF5 file. No support planned for special HDF5 data types, e.g., compounds & c, except in the context of native data types. (b) Integrated with cURL, so rlab can now read, download and upload web pages and files to and from local filesystem and into the memory. (c) Limited support for sockets, and their read and write operations. 2. More code cleaning and more glitches removed.
