Re: is there computer algebra system module?

Depending on what you need, there are several libraries in C and C++ that 
should be wrap-able. For instance, [CoCoA](http://cocoa.dima.unige.it/), 
[Singular](https://www.singular.uni-kl.de/), [LinBox](http://linalg.org/), 
[Pari](http://pari.math.u-bordeaux.fr/), ... . Each of these is _very_ likely 
to be the best at some aspect of what it does, because they are all developed 
by leading researchers in the field.
