Math Eclipse Plugin

Java Computer Algebra System. Features: math expression parser and evaluating API (jsr223), generic nested lists (i.e trees) API, pattern matching. Moved to http://code.google.com/p/symja/

mate-j2me

A MIDP2-based mobile Computer Algebra System. MATE is designed to help engineers with routine math tasks. It's too an easy and inexpensive way to have a graphing calculator in your pocket.

franklinmath

Franklin Math is now available!Franklin Math is an open source symbolic computer algebra system (CAS), with similarities to commercial math packages such as MATLAB or Mathematica. It handles some symbolic algebra and manipulation, as well as numeric calculations. The built-in functions cover ... [More] several fields of mathematics, and allow for function plotting. I have tested the installer on Windows XP without any issues. On Linux, you may have to be logged in as a root/administrator to have shortcuts created properly. On a Mac, the installer (generated with IzPack) does not support shortcut creation yet, so you will have to make your own (be sure to set the working directory to Franklin Math's install path). [Less]
