This looks like a problem with an Octave Forge package, not a bug
in Octave.  The correct place to report this problem is the
Octave Forge mailing list, octave-dev@lists.sourceforge.net.

A copy of this update to the bug report is being sent to that
list so that they are aware of it.  Please follow up there.

The package optim-1.0.12 contains a function fminsearch.m which is obviously an attempt to provide functionality along the lines of Matlab's "fminsearch".  The Octave version, however, contains a "grad" argument that is not present in Matlab's calling sequence.  I suggest deleting that argument to make the call more similar to Matlab's.  The "grad" argument has no function in the Nelder-Mean minimization scheme that fminsearch uses.  I attached a diff -c file for the change I have in mind.
