How can I check if something is a matrix?
The best I've come up with so far is:
x in MatrixSpace(SR,n)
But it doesn't work for arbitrary dimension. (Am I right in assuming that SR is the most general thing one can define a matrix over?)
You can do this:
sage: from sage.matrix.matrix import is_Matrix
sage: is_Matrix(1)
False
Even better, don't check for types in your code. If an argument behaves like a matrix, then your code works. If not, an exception will be raised. Thats how its supposed to work.
