GNU Maxima is a free
computer algebra system, written in
Lisp and released under the
GNU General Public License. It is based on an early version of
Macsyma, and was maintained by
Bill Schelter from
1982 until his death in
2001. It is now maintained by a group of volunteers at
Sourceforge.
The GNU TeXmacs mathematical editor program can be used to provide an interactive graphical user interface for Maxima.
