[Octave-patch-tracker] [patch #8918] fgridsearch as a gridsearch alternative to fminsearch

[Max Görner]

Follow-up Comment #3, patch #8918 (project octave):

I improved the documentation a tiny bit. Most importantly, I added another
example which demonstrates more clearly why I consider fgridsearch to be
beneficial. I'll copy the example here for convenience:

++
%Here fgridsearch is used to explore several starting points for a
%fminsearch optimisation. That way the global minimum is found.
fh = @(x) -10*exp(-(sumsq(x - [-100 -100]))) - 3*exp(-sumsq(x));
gh = @(x) nthargout(2, @fminsearch, fh, x);
range = linspace(-200, 200, 10);
[params, fval] = fgridsearch(gh, range, range);
--

I have to admit that this function only helps to hide loops, though.

If the new example makes the function interesting, I'll happily work on the
other points.
