Ok. I found that the new fminbnd function is part of the development version of Octave at the moment: http://hg.savannah.gnu.org/hgweb/octave/file/62bb59f927b1/scripts/optimization/fminbnd.m It seems like this implementation of the function uses the Golden search method combined with parabolic interpolation (like in Matlab's fminbnd). This means that the new fminbnd function should be faster that the one in the Octave optim module. I just tested the new Octave fminbnd function quickly and its speed and accuracy seem similar to those obtained with the Matlab function. The new fminbnd function seems superior to the old one found in optim.
