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.
