I thought these were called algrebraic manipulators or is that something different? --(talk)BozMo 13:32, 14 May 2004 (UTC)
IMHO it's important to show which software packages are free software - what's the point of having wikipedia under the GFDL if we are not going to be supportive of the same sort of freedom in software? Boud 12:18, 10 Aug 2004 (UTC)
- I don't quite agree with your reasoning, but I do think that we should include a very short description of the software packages in the list - including its freeness. I tried to mark some more packages as free, but I have some problems with the templates: sometimes, {Free software} renders as Template:Free software (see the article). Any suggestions? -- Jitse Niesen 12:16, 11 Aug 2004 (UTC)
Looks like templates only get properly referenced five times (as of today's date anyway) Boud 15:07, 10 Sep 2004 (UTC)
- Template:Free software,

So we need to discuss this with someone involved in coding...
There's a discussion here: http://bugzilla.wikipedia.org/show_bug.cgi?id=95 Boud 15:17, 10 Sep 2004 (UTC)
Shouldn't Magma be listed under algebra, group theory along with GAP? I don't think you can do much else with it...
- From five minutes' reading of the wikipedia pages on GAP and Magma, it looks like you're right, but it sounds like you know more about these than i do. IMHO you should make the correction. Boud 13:58, 4 Oct 2004 (UTC)
Done. What's the rule on removing completed discussions? --64.5.123.248 19:51, 28 Nov 2004 (UTC)
Why are the 'numerical' systems Matlab, Octave, MathCad, and SciLab listed here at all? Of these, only Matlab has some symbolic component (it includes a Maple module -- optionally?). The Octave page explicitly says it is not a computer algebra system....--Macrakis 02:36, 18 Feb 2005 (UTC)
- I've cut the list of numerical and statistical systems. For the record the list was: MATLAB, GNU Octave, Scilab, Mathcad, S (programming language), R (programming language). Of these, the symbolic capabilities of Matlab are provided by Maple; R has very rudimentary capabilities (I think it can compute derivatives and nothing else), and I don't think the others have any symbolic capabilities at all. So these are out of place in a discussion of algebraic systems. For what it's worth, Wile E. Heresiarch 05:49, 16 Mar 2005 (UTC)
Automatic differentiation link
I think the automatic differentiation link that was just added is out of place here. Automatic differentiation is a technique for numerically maintaining one or more differentials through a calculation. Symbolic methods can be useful in deriving automatic differentiation programs, and for all I know there may be CASs that support automatic differentiation, but it is not specific to CASs. I'd compare this to calculating with numeric intervals -- again, a function which CASs may support (just as they support floating-point arithmetic), but not specific to CASs. Unless someone has a convincing counterargument, I will remove the link in a day or two. --Macrakis 21:40, 28 Mar 2005 (UTC)
