Good, free CAS for UNIX?

Good, free CAS for UNIX?
Does anybody know of a good, free (as in no cost) CAS for UNIX?

I have mostly non-Intel boxes and would be interested in finding a CAS to run on one or more of them for occasional use. The latest incarnation of Macsyma looks like it might be a good candidate. Any other ideas?

Xcas would probably be very good since it comes from a trustworthy source Smile but I don't see my platforms listed and I don't see how to get the source code.

Thank you.

[OT] Mathematica free for Raspberry PI
It's a little slow though.

Cheers

I was once using Maxima http://maxima.sourceforge.net

Not sure how it compares to others. For my use cases (symbolic matrix calculations) it was good enough ;-)

If you're not running anything too heavy, sage math cloud or Wolfram Alpha are zero install..

Sage has sympy and maxima available.

I believe this is the page you're looking for, Giac being the engine underlying Xcas (and it appears that Xcas is included in that source bundle): http://www-fourier.ujf-grenoble.fr/~pari...tml#source

Reduce is extremely good and extremely powerful. As it has no bells nor whistles it doesn't get the appreciation it deserves. It's a 45 year old CAS focused on A, so no graphing, there's gnuplot for that.

I read about that briefly earlier. Very nice that they give a free license. But probably not very useful.

This is the one that I noted above that looks most promising on non-Intel.

Absolutely NO CLOUD AND NO GOOGLE HERE!. But for occasional light use the Wolfram site is really cool.

It is not clear to me whether Giac has any front end (I think that's what Xcas is). At this point I don't think Giac is going to be useful alone. And unfortunately there are some nasty GPL pieces that are painful to build anywhere but Linux because of non-portable development practices gcc-isms and other GNU-dependencies. I generally keep my systems as GNU and GPL free as possible, so this is probably not going to be a good choice for me.

This might be good if the platform I want to run it on is supported. It says it is based on two variants of LISP (both of which are obsolete since about 1989/1990 when Common Lisp won) but they are included in the source distro. If I can't get Macsyma to work then I'll look into this.

Thanks guys for all the suggestions.

maxima is good as a cas but I would hesitate to use it primarily for matrix operations. Octave is FAR better for that.

As an alternative, Geogebra is a nice package including a CAS. Maybe not the most powefull CAS on earth but well integrated within this software. Can run on any machine supporting Java.

Thank you. I usually avoid Java like the plague but in this case the box I want to run a CAS on is actually a good Java platform. I will take a serious look at this.

It is actually giac in the background... (the cas part)

Geogebra's CAS stuff. All driven by giac.

Is the Geogebra's CAS poor compared to Maxima or Octave??? I used it often for Geometry and I don't see a great CAS...

Thank you! The general reply button strikes again Wink
