There was a subsequent discussion. > I simply don't see a Matrix as a container of ndarrays That is hardly an argument. Remember, any indexing that when applied to an 2d array would produce a 2d array will when applied to a matrix still produce a matrix. This is really just principle of least surprise. Or, if you want a complementary way of looking at it, it is keeping as much of the natural behavior of the ndarray as possible while adding convenient submatrices, matrix multiplication, and inverse.
