Since you and Mark have already used sympy for code generation, you already know how to do things -- would you be willing to prepare patches with functionality that you think should end up in sympy? It'd be very useful to many people. If not, you'll have to wait until someone else does it. :) Ondrej --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
