I looked at the code and understood enough to know that the question I
have is a little off-topic but I will ask it anyway. Suppose I have
numerically evaluated the Laplace transform of some function of t and
therefore have a big table of the transform for real values s. How can
I invert this numerically? (Not by using any form of contour
integration as Fernando's algorithm does, I think because this will
ask for complex values of s.)
