Matrices strike me as a bit of an anomaly. I would expect an
N-dimensional container to contain (N-1)-dimensional objects. But
matrices cannot have dimensions less than 2, (and in numpy, can't have
dimensions higher than 2). So, to me these operations don't make much
sense. Is a matrix then more of a collection of matrices than a
container of matrices?
I'm glad we have the ndarray concept in numpy where these concepts
consistently make sense.
