Follow-up Comment #14, bug #52685 (project octave):
The "by" symbol looks good in LaTeX. In plain text, I guess I'm sort of used
to seeing m x n. However, I started using m-by-n in the patch, especially in
cases where there were a lot of variables involved. It's more a visual
digestion sort of thing. Without the hyphens, it starts to be: x is t x k, e
is p x t, y is k x p, and c is kt x pt. It looks like one big strung-together
set of foreign letters.
Upper case versus lower case matrix size parameter isn't too critical for me.
I'm comfortable with either so long as it is consistent in a particular
function doc. In signal processing, we typically use upper case limits,
especially N. But in pure math, it's often lower case limits.
I think the upper-case, lower-case variable meaning matrix vs. vector vs.
function input variable question is more critical.
In the ols.m documentation, I think I'll change use of "vec(e)" to just plain
"e", i.e., @var{e}. I don't know what was meant--if anything--by the vec()
function. kron(s,I) I think is simply supposed to be "s I" in math speak,
that is the residuals are independent with the same variance. But right, one
typically would write s^2 I where s is standard deviation (of a normal r.v.).
