Dear all, I'm sorry if this is a 'utfs' question, but I couldn't really find a clear answer. I would like to do some numerical operations on a Sage function (/expression) provided by the user (i.e. typed in the notebook). Ideally I would like to have this function available as a Cython function to perform these operations (assuming say the input is a composition of only 'elementary' functions). So say the user enters 'f(x)=x^2' I would like to have a Cython function like
cdef f_ cython(double x): return x**2 so that I can run other Cython functions that evaluate f_cython (a lot). Is there a standard way to do something like this? If not, I guess I could try producing the code for the Cython function definition as a string and then call eval(...) on it or something like that? What would be the best way, keeping an eye on optimisation for speed?
