The FEMM 4.2 distribution includes toolboxes for interacting with FEMM from Octave/Matlab, Scilab, and Mathematica.


For Matlab, add the mfiles directory with the interactive pathtool command.


Recommended distributions of Gnu Octave that run on Windows are:

FEMM needs the Octave-Forge "Windows" package to efficiently communicate with Octave. In recent versions of Octave, Octave-Forge must manually be select during install:

After installation, you'll need to add FEMM's mfiles directory to Octave's search path:

Scilab can be obtained from The SciFEMM interface is automatically included in every installation. 64-bit FEMM requires 64-bit Scilab for the the two programs to successfully communicate (and 32-bit FEMM requires 32-bit Scilab).


The MathFEMM interface to Mathematica has been tested on Mathematica 7, 9, and 10 though it may work on other versions. The package works with either the 32 or 64 bit versions of Mathematica.
