Hi all! I am trying to do simple convolution:
x = PolynomialRing(QQ,'x').gen() f=piecewise([((-1,3),1*x^0)]) g=piecewise([((0,5),exp(-x))]) r=g.convolution(f) and got this error message: RuntimeError: Symbolic Ring still using old coercion framework What is wrong with it? --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
