[PyGiNaC-users] matrix utils and new tests

[<pp...@fy...>]

Hi, 

I would like to suggest the attached patch (matrixutils.patch) which 
exports the matrix utility functions unit_matrix and symbolic_matrix. The 
exporting is made by using the GiNaC equivalents, although at least the 
former one could also be readily implemented in Python. 

I also pythonized some new GiNaC regression tests, which are attached.

Best Regards,
Matti
