Don't be silly. There's nothing like a "suckless" CAS, at least
nothing remotely approaching the simplicity of suckless.org
software. Computer algebra and calculus are complex and
computationally intensive. They can't (and arguably shouldn't)
be simplified beyond a point.
How is gnuplot? gmp bignum library? Maxima? Sympy? Octave? Ever used
any of these?
Maxima is pretty much the gold standard among open source CASs.
Sage is a bit more featureful in some areas, but it's a
ridiculously huge, self-contained distro including an entire
Python runtime, and it pretty much requires that you use the web
interface to do anything useful. Sympy is the basis of Sage, and
it works, but it's a bit slow and lacks a few features.
gnuplot is not a CAS, it's a plotting system. It's generally
pretty god awful, but it's usable with Maxima as a frontend. gmp
is just what you've labeled it as: a bignum library. It handles
arbitrary precision arithmetic, not algebra.
Scipy and Numpy are useful for certain CAS features, and will at
the least replace Matlab (which really isn't that useful,
anyway). The TI and HP calculators have decent CASs, too, if
you don't need anything too fancy. I know that there are a few
other simple CASs laying around, but they're generally pretty
weak, and probably won't do what you want them to (for pretty
much any realistic value of 'what you want them to').
There are also some nice libs in Haskell, which have the benefit
that Haskell is pretty much tailor made for mathematics, but I
really can't speak to their full-featuredness.
Use Maxima, try Sage, but if you want suckless, prepare to be
disappointed by the latter.
I'm too much of a n00b (and I'm still trying to wrap my mind around
what it means for software to suck less) to actually tell if some code
does, in fact, suck less.
Maxima's code is more or less brilliant, but it's Lisp, which is
a completely different world.
