Indeed. It should not be difficult, I'll try to give it a shot in the comming days. If I get something, I'll let you know. Ondrej P.S. We are interested in any feedback you have when playing with SymPy. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
