[SciPy-user] symbolic variables

[Ryan Krauss]

Is there a way within SciPy to do symbolic math - sort of like the 
symbolic toolbox of Matlab that interfaces with Maple?

I need to be able to work with matrices that have at least one symbolic 
variable in them.  Most of the time, all of the variables will be 
assigned numeric values, but occasionally I need symbolic output.  It 
would be great not to have to do all of this twice in two different 
pieces of software - one for numeric and one for symbolic.

If this can't be done in SciPy, can anyone recommend a good symbolic 
program that can do matrices?

Thanks,

Ryan
