This touches the subject of inconsistency with math.add as one example. One of my "favorite" peeve's is how the size (shape) is given to functions that generate matrices. In some functions the size is given as a tuple, in other the size in different dimensions are given as seperate arguments. Here are some examples:
To to create an array with shape M, N you do: zeros((M, N)) ones((M, N)) rand(M, N) eye(M, N)
I'm sure more examples exists.
Yep, repmat(A,M,N) is another one. http://projects.scipy.org/scipy/numpy/ticket/292 But I think you'll find that rand at least is no longer there. Instead you're supposed to use random.random((M,N)) eye(M,N) is considered to be ok, because 1-D eye is pretty useless, and it's not clear what you'd want out of N-D identity matrix. There has been a lot of discussion about trying to unify on shape args always being tuples. --bb
