open source equation solver?

[Walter Harley]

I'm looking for a free (preferably open source) algebraic equation solver,
for the Windows platform. I don't need vast power; just simple equations of
the sort that I could solve myself if I weren't so lazy and error-prone.
Presumably, something like MAPLE, but considerably less powerful and
infinitely less expensive.

Does any such beast exist?

I don't know about a free version, but Derive will do what you want and
is a lot cheaper than Maple or others (especially if you are a student
or teacher).

Here is one link.

Look into MuPAD and scilab. Both available for free.
I know they run under Linux, but I think they are also
available for 'doze.

Look into MuPAD, and scilab. Both are available free and probably as
powerful as MAPLE. I am using them under Linux. I believer that
versions are available for 'doze.

Thanks, xray and Chuck, for your suggestions!

I'm in the unfortunate position of being (a) commercial, (b) honest, and (c)
poor. Derive looks like it's a bit under $200. MuPAD has a 30-day eval,
and a free license for non-commercial users, but the commercial license
looks like around $500. Both reasonable prices but more than my little
company can easily spend.

Still hoping to find an open source product... if not, I'll check out
Derive.

Hi Walter,

Look into MuPAD's definition of what a commercial license is,
and I think you will find that you are not commercial in their
eyes.

I wrote one about 12 years ago, Walter. I've posted the .exe version
to a.b.s.e under this same subject title. It's free if you can use it.
Check it out.

Thanks, Paul. Do you have that available somewhere? Binary newsgroups like
a.b.s.e aren't archived anywhere that I know of.

Thanks, Chuck. Where do you find this information? I've been searching
their site(s), both mupad.com and mupad.de, and I can't seem to find
anything specific about that. The closest I came is that the free license
applies to "students, teachers of public schools and universities, to
researchers and scientists of universities and non-commercial, non-profit
research institutes, and to private individuals only." I'm a commercial
enterprise - at present I'm the only employee, and I'm not making any money,
but my intention is for both of those conditions to be temporary

Maxima is a very capable open-source computer algebra system:

Great. Didn't know anything about that. I love it when the internet
realy works like I once hoped it would. I will check this out.

I think I am too clueless to help in any way with the development, but I
would if I could.

I'll mail it to you. I can't guarantee it'll port well to your
platform but it won't take a minute to try it!

Using Chuck's and xray's suggestions, I did this
http://www.google.com/search?&q=Derive+MuPAD+MAPLE+gnu+OR+open-source+Octave+Axiom
and got this
http://66.102.7.104/search?q=cache:xa1xMtm5ZkMJ:www.economics.ltsn.ac.uk/software/maths.htm+applicable-free
which says MuPAD and Octave are free.

Well, a quick look at MuPAD's web site will assure you that it is *not*
free, for commercial users; the price is US$500, if I remember correctly.
There is a free 30-day trial version, and they offer free licenses for some
of their products for non-commercial users. I have not been able to find
their definition of "commercial."

Octave appears to be for numerical solutions - I'm hoping for something that
can do symbolic math, that is, that will give me an equation rather than a
number.

But Maxima, suggested in another post, looks like it will work great!

Thanks, all.

Yeah, I was going to mention Scilab. It's an outstanding clone of
Matlab available for free on both Windoze and Linux. I use it all the
time.

http://scilabsoft.inria.fr/

One thing about Scilab: It is really oriented towards numerical math
& signal processing. It can solve equations, but not really
symbolically in the same way in which e.g. Mathematica can. I use it
for stuff like simple & complex numerics, finding complex roots of
rational polynomials, and so on. I don't think you can use it for
symbolic integration like Mathematica, Macsyma, or other symbolic
manipulation packages. Its utility to you will really depend upon
exactly what you want to do.
