I would just use regular symbols for that and differentiate them and then substitute them for functions. I would like to have a library for that, so if you'd like to contribute one, we'll help you out. :) Ondrej --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
