Actually, fixing this just involves fixing https://code.google.com/p/sympy/issues/detail?id=1799, because Pow already has this logic (_eval_power).
Oh, and I guess Matrix._eval_power would need to be implemented (currently it raises NotImplementedError, but this is easy to fix, just make a**Matrix give exp(log(a)*Matrix). Even with that fixed, you could do E**Matrix, before issue 1799 is fixed. Aaron Meurer On Mon, Jun 24, 2013 at 12:37 PM, F.
