Because of the subject of this thread I feel justified in giving the following examples from Axiom: http://axiom-wiki.newsynthesis.org/ManipulatingExpressions Perhaps Sage can implement some form of pattern matching and subsitution such is done by Axiom's rewrite rules? I think that in many respects these provide a functionality similar to Mathematica. There is also a similar re-writing system in Maple (applyrule). > ... > On Aug 20, 11:38 pm, William Stein wrote: >> On Wed, Aug 20, 2008 at 9:37 PM, mhampton <[EMAIL PROTECTED]> wrote: >> >> > I used to really enjoy writing programs in mathematica, but maybe >> > I'm a strange person.
