The fminsearch.m function in the Optim-1.0.12 package is clearly
designed to implement functionality substantially identical with
Matlab's fminsearch function. But Matlab's fminsearch does not have the
"grad" argument -- I think it is a holdover from an ancient version of
Matlab when it was called "fmins". I suggest that argument be removed.
A diff -c file with proposed changes is attached.
