When you use the profiler in Matlab it is generally done through a

I don't know if that's how it's generally done. The guy who provided
me with the profiler output said he never used the Matlab GUI much. I
don't think it's so important to worry right now about how the Matlab
GUI for profiling works as it is to make sure we collect the same (or
more!) information and then somehow present it nicely, whether gprof
output to process later with some other tool, or some other format we
can think of, and we have the same callable functions as Matlab.
I wasn't implying the profiler GUI was essential or needed at this
point. I've certainly never used the profiler without the GUI though,
perhaps I'm unusual. Obviously it is much more importent to have the
profile function.
personally I would leave profile as it is (since one of aims of
octave is to match the matlab syntax in most cases) and have a
separate function do the text display, or alternatively add an
option to profshow.
What do you mean, "as it is"? As the code that Daniel just submitted?
Well, I assumed you will be matching the matlab profile function syntax,
and that this will be the ultimate aim. I therefore meant 'as the matlab
syntax is'.
If doing a text display I would consider having an option of a text
file to output to, as the results could be a hell of a lot of text
to display in the output window in many cases.
If there's too much text, that's what pagers are for. But I don't
generally see people wanting to see profiler output in plaintext
formats. Plaintext is usually something you feed to gprof or whatever
else we come up with that then produces the graphs and the summaries.

Sure, I was just throwing in some (possibly useless) thoughts. Feel free
to ignore.
Incidentally I'm really glad you guys are working on this, it will be
a great addition! So thanks.
