You might find out a lot from reading through this page:
http://www.scipy.org/NumPy_for_Matlab_Users
What I think that doesn't say is why the two classes are needed in
NumPy. Basically, the reason for that is that Matlab has .* and *
which mean different things, but Python only has the one * operator.
Some people think that should mean .*, some want it to mean *. So
NumPy offers two different classes with different behavior instead of
two different operators.
