It seems to me that Dirac delta is not appropriate here since it is a 'generalized function' of a real variable only in SymPy. Probably some new class of objects, formally integrable over a complex domain, would be needed to implement this idea. -- You received this message because you are subscribed to the Google Groups "sympy" group.
