Related Tools

The FEMM 4.2 distribution includes toolboxes for interacting with FEMM from Octave/Matlab, Scilab, and Mathematica. Recommended distributions of Gnu Octave that run on Windows are:

• QtOctave 0.7.2 Distribution. Gnu Octave 3.0.0 with a nice front end.
• Gnu Octave 3.2.0 Distribution. (Make sure that Octave-Forge is selected for installation)
• Gnu Octave 3.0.3 Distribution.

These distributions are recommended because they come with the Octave-Forge "Windows" package. This package speeds up the communication between Octave and FEMM.

Scilab can be obtained from http://www.scilab.org/. The scripts included in the FEMM distribution have been tested on 32-bit versions 5.2.2 and 5.3.0-beta 4.
