The Maxima system (FSF GNU project)

The Maxima system

Maxima is not only one of the oldest and best computer algebra systems around, it is also one of the only general purpose systems for which there is a free implementation. The current free Maxima implementation was started by William F. Schelter. It is dedicated to his memory. Here follow some features of Maxima:

Plotting via netmath over the network.
Computations over network
Well tested on a large array of problems.
Source level Debugger for maxima code
Documentation available as html, texinfo, info, dvi and postscript. The documentation can be read inside TeXmacs.
Easy to extend in fundamentally new ways, because you have complete access to source, and access to Common Lisp.
Portable to many systems.
