FriCAS is an advanced computer algebra system. Its capabilities range from
calculus (integration and differentiation) to abstract algebra. It can
plot functions and has integrated help system.

FriCAS 1.0.8 builds on Linux, many Unix like systems (for
example Mac OSX and Solaris 10) and Windows.

FriCAS is build on top of Common Lisp; several Lisps can compile
and run FriCAS -- currently supported are GCL, SBCL, Clisp, ECL,
Closure CL (former OpenMCL) and CMU CL.

Notable changes (compared to version 1.0.7) include:

- Improved version of guessing package. It can now handle much
larger problems than before. Added ability to guess
functional substitution (Mahler) equations.
- Experimental support for build using CMU CL
- Various speed improvements including faster indexing for two
dimensional arrays
- By default FriCAS build tries to use sbcl.
- Building no longer require patch.

Bug fixes, in particular:

- correct definition of random() for matrices
- conditionals in .input files work again
- Spad compiler now recognizes more types as equal
- fixed problem with pattern-matching quote

What's the license? The website doesn't say.

Downloaded from CVS and rebuild it. Works fine, but seems archaic.
The document system uses Xt with Athena widgets!
Brings my back to the Sun 360 I used when I started studying computer
science back in 1987.Seems to me the whole thing could be replaced with a
web interface.

I have not looked, but that it uses a simple interface would make it fast and small.
WTF would you cripple anything with a web interface that you only use for local algebra?
Oh wait, Vista needed more hardware too?

Because "web interface" is the latest fad and everything has to have
one perhaps. Also makes a nice buzzword, especially if used with
web2.0.

FriCAS user interface is small. But I would not call FriCAS small,
version for AMD64 Linux takes 200 MB disc space (about 130 MB of
executable code, the rest is documentation, binary data and images).
The main executable needs about 80 MB of RAM when doing simple operations.
It is possible to create version which needs less disc space (105 MB)
but this version is much (on average 7 times) slower -- fast version
is compiled to native code, the smaller one uses bytecode.

FriCAS offers a lot of functionality, there is simply no way to
to this in really small system (say few MB). And while it is
possible to save a lot of space at cost of speed, it seems that
on modern machines big and fast version is better than small and
slow.
