We're pleased to be announce the availability of FreeMat 3.5. Here is the list of changes since 3.4:
* Fixed path detection problem on win32 (forward vs backward slashes)
* Added ability to change the scrollback length via edit->preferences menu
* Fixed diary command so that commands are echoed as well as their outputs
* Fixed diary so that the commands are echoed as well as the outputs.
* Added fflush command.
* Added ctrl-w to clear the current line
* Changed sort algorithm to a stable one.
* Fixed bug in linspace
* Added the new ctype interface - thanks to Scott McOlash for suggesting it, and GE Global Research for letting us release it under the GPL.

FreeMat 3.2 has been released - it fixes some library dependency issues on the Mac, and some build issues on Linux.
The latest version of FreeMat (3.1) has just been released. Beyond the usual bug fixes, this version of FreeMat includes a new Threading API, which allows you to take advantage of multi-core and multi-processor machines from within your FreeMat programs. You can also perform powerful Perl-style regular expression manipulations in 3.1 using the regexp command, and its variants. A new, unified multi-platform regression test suite is now shipped with FreeMat (as the run_tests command), which allows you to verify the functionality of your installation. Plotting functions have been improved through the use of an explicit double-buffering technique which eliminates flicker during plot updates. Note that to increase compatibility with MATLAB, you must now include explicit drawnow commands to get updates within scripts. FreeMat also has new functions for reading URLs, and parsing HTML and XML files. The help window has a search tool now to help you quickly locate functions and help topics. The memory usage of FreeMat has been significantly improved - so that FreeMat operates with less memory and should run faster than previous versions. Also, you can now specify a script startup.m that is automatically executed at startup time.
The Mac bundle was flawed. I have uploaded a fixed version. Thanks to Masahiro Takatsuka for pointing out the problem.
The current release of FreeMat is 3.0. It represents a significant improvement over the prior release (2.0). Here is a partial list of the changes:
MATLAB-style GUIs and Widgets
Speed improvements (loops and indexing operations are 10 to 100 times faster)
A new parser that recognizes more of the MATLAB syntax
A debugger that is integrated with the editor
Support for 64-bit integers
Improved MAT-file support
Universal binary support for Mac OS X
New graph/plot tools to rotate, zoom and pan plots.
Builds are now based on ATLAS for improved matrix performance
Various bug fixes.
A new release of freemat is now available from the website http://freemat.sf.net. This is primarily a bugfix release, although some new features have been added as well. The release notes are below:
FreeMat has reverted to the autotools build system. Hopefully this will solve some of the build problems people were facing with the 2.0RC1 release. This release adds many new MATLAB-compatibility functions and scripts (special thanks to M. Vogel for the help). A number of finite-precision related bugs were fixed in the range operator (: and : :). Support for reading and writing csv files was added. The output format code was rewritten to make more efficient use of the screen. The default Qt style was set to plastique on X11 platforms (use the -noplastique flag to override). Text-based help was fixed on all platforms. Support was added for a traditional Linux install (non package based) that should adhere to the LSF rules. ... read more
Its been nearly a year (!) since the last release of FreeMat. A new version is now ready for testing. I have elected to release it as a Release Candidate instead of a full release because of the significant changes that have been made since version 1.10. Please post support requests/bugs or feature requests to the usual place http://freemat.sf.net. Here is just a short list of the new features.
* Handle-based Graphics including 3D surface plots, multiple plots per figure, and full customization of axes properties. Preliminary support for OpenGL rendering.
* Support for MATLAB-style classes and object oriented programming, including operator overloading.
* New GUI interface based on Qt4. FreeMat now sports a new terminal interface, a highlighting editor, and some new tools.
* Speed improvements and optimizations (some loops are 10-100 times faster).
* Preliminary support for reading and writing MATLAB .MAT files.
* PDF output on all platforms.
* New build system based on qmake.
* Many new MATLAB-compatibility functions and scripts.
* Native Aqua application on Mac OS X.
* Linux distribution now includes a binary release that should run on several distributions.
* Over 200 new pages of documentation, and an improved built in help browser.

FreeMat 1.07 has been released! This version is a major enhancement over 1.06, and includes more linear algebra support (QR, SVD, generalized EVD, etc.), a host of new random number generators, special function support (gamma, erf, etc.), support for creating stand alone binaries from scripts on Linux, enhanced plotting functions, and better error reporting. Check out http://freemat.sf.net for details.
A critical bug was found in 1.05 that broke code using the pass-by-reference feature of FreeMat. Instead of replacing the 1.05 images and risking a fractured release, I opted to post a new one. The next release will be more substantial.
An updated version of FreeMat is now available. Besides a number of important bug fixes, this version features better error reporting, a functioning MPI interface (for parallel algorithm development) and a Mac OS X bundle.
FreeMat version 1.04 has been released. It includes an MPI interface that allows you to develop parallel and distributed algorithms using the Message Passing Interface standard in the comfort of a FreeMat environment. Note that there is currently no MPI support for Windows.
A new version of FreeMat has been released. This is a minor bug fix.
FreeMat 1.01 (a minor bug fix and repackaging of the source) has been released. The website freemat.sf.net has also been posted.
I have removed the Un*x source code package from the release. There is a problem with the build and I am trying to sort it out. Will upload the updated package as soon as possible.
FreeMat 1.0 has been released. FreeMat is an interactive, fully functional environment for engineering and scientific applications.
