I also discovered Sage an open source math program written in python http://www.sagemath.org/ I haven't done anything with python before, but I have some friends who rave django, so it may just be easier to go that route. Either way I'll let everyone know what ended up meeting my needs. -- Posted via http://www.ruby-forum.com/.
