SymPy can handle derivatives just fine. You just need to express your
function as a function of whatever variables, for example:
>>> f = Function('f')
>>> f(x, y, z).diff(x, y)
D(f(x, y, z), x, y)
One thing that unfortunately will not work very well is the chain
rule. This is because we currently do not have a way to express the
derivative of a function evaluated at a point. See
http://code.google.com/p/sympy/issues/detail?id=1620.
We do have a code generation module, but someone else will have to
tell you more about that.
