Bill, I think I see what you mean. Nevertheless, I prefer my vectors to
have a row-or-column orientation, for example because the requirement of
conforming shapes for multiplication reveals (some of) my bugs when I
slice a vector out of a matrix but along the wrong axis. It seems that
otherwise I would get a bogus result without necessarily realizing it.

I guess that also tells something about my inefficient matrix coding
style in general, but still... For rapidly implementing some published
formulae I prefer to map them to (numpy) code as directly and
proof-readably as possible, at least initially. And that means with
matrices.

cheers,
