RE: Toolboxes

Hi Michael,
This is what I used
[theta, obj_value, convergence] = bfgsmin("objective_fun2",{x0,y0,z0,w0},control);
so I guess it is bfgsmin. If there is a newer equivalent function or if I need to install a newer
version of Octave I will gladly do it ( I may ask for some help though)

Thanks
Cheers

Gino

Which function were you using? If it was bfgs.m, which to my knowledge is the
only optimization function that has disappeared, that was replaced a while
ago by bfgsmin.cc, which compiles to bfgsmin.oct. This _does_ work on
Windows, at least with the version of Octave for Windows that I tried out. If
you would like the old bfgs.m file, you can get it from
http://cvs.sourceforge.net/viewcvs.py/octave/octave-forge/main/optim/bfgs.m?rev=1.11&view=log
by selecting version 1.10.
