Yes, that certainly meets the need.
In previous applications, I never thought to use Vector because it was
sufficient for me to adopt the convention of a column vector to
represent XY points. That way, I could do things like c * R * u + t.
Isn't that simple? Not only is it easy on the eyes, but i

Right, I was confused because I saw:

Hi all,
We currently use an array scalar of value False as the mask in
MaskedArray. I would like to make sure that the mask value cannot be
modified, but when I try
import numpy as np
x = np.bool_(False)
x.flags['WRITEABLE'] = False
I am warned that you "Cannot set flags on array scalars.". Is

Thanks for the explanation of bzr. I'd like to give it a try on
another project. How did you create the repository at

Why not consider a matrix with a shape
of (1, n) as a row vector

Probably in scipy.special and or umathmodule.c in numpy/core/src. The
key is to register a 1-d "inner" loop that performs the basic
calculation for a particular data-type.
You also need to provide
