Hey Ondrej, Yeah, I don't think the symbolic stuff was really designed with that in mind. Your best bet would be to go through the symbolic types in calculus/calculus.py and add a _recursive_sub_expression(self, to_match, replacement). --Mike --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
