Comment #16 on issue 2106 by Vinzent.Steinberg: Matrix of shape (1,1) and a number can't be added
http://code.google.com/p/sympy/issues/detail?id=2106
The problem with defining addition componentwise is that you'd expect (1 + X) * Y = Y + X*Y.
Why? It's clear in Python that 1 cannot be the unity matrix, so I wouldn't expect distributivity here.
Even if it was misleading, it would be consistent with numpy. -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
