[Numpy-discussion] Best representation for array of points, or, how to distinguish a Nx1 array of points from a Nx3 array of scalars

I've found that there are two ways to represent an array of 3D points: # 01: N = 4 a = numpy.zeros((N, 3), dtype='f8') # 02: N = 4 b = numpy.zeros(N, dtype='3f8') The second representation seems "conceptually" better, it is really an 1D array of N elements ( i.e., b.shape == (4,) ), but, "in
