My reading of the above hiccupped at around "Besides, octave also
uses...".
Checking the differences in patterns, I think
... the same as matlab, except that '%%%' and '##' can also
be used to begin code sections, in addition to '%%' that is
understood by both.
may be easier to read. It makes it clear that you'd want to stay
away from %%% and ## if you want to be compatible.
Thanks.
