[Numpy-discussion] adaptive sampling of an interval or plane

We should also talk to Ondrej about this at SciPy. Both sympy (through
mpmath) and mpmath have matplotlib based function plotting. I don't think
it is adaptive, but I know mpmath can handle singularities. Also, Ondrej is
doing doing his graduate with with a group that does adaptive finite
elements, so he would also be familiar with such algorithms. I am sure that
sympy and mpmath (Sage too as well) would be some of the main users of
function plotting and would love to see this happen.
