Hi TsoMin,

the Octave manual is not the right place to get informations on a
package. For the optim package, you can try 'optim_doc' from the
Octave command line, or just 'help lsqnonlin' for your case. The
optimisation options are not defined by the 'optimset' function, but
by the individual optimization functions.
