Latest News - 2013-06-30 - FreeMat 4.2 Released

We are pleased to annouce the release of FreeMat 4.2. This version includes a number of bug fixes and some cleaned up tests and documentation. Here is a brief list of changes:

  • FreeMat is now (hopefully) easier to build. The top level README.TXT includes instructions on how to build FreeMat on all three platforms (Linux, Mac OS X, and Mingw32).
  • Documentation has been migrated to doxygen.
  • A number of improvements have been made to the JIT back end.
  • 64-bit on all platforms!
It's not a long list, but given the nearly 2 years since the last release, 4.2 is an important one. Comments or problems should be reported to the mailing list or filed as bugs on the website.


These are quite dated and need to be replaced.
