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 the

Hi,
I started a page on how to use bzr, with a link to an import I have
done on the numpy trunk:

I thought it would be useful for people not familiar with DVCS, and are
curious to try. In perticular, since I have

Hello folks,
In the course of a project that involved heavy use of geometry and
linear algebra, I found it useful to create a Vector subclass of
numpy.matrix (represented as a column vector in my case).
Why not consider a matrix with a shape

The array scalars are always read-only anyway. So, there should be no
reason to set this flag.
Right, I was confused because I saw:

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
