Hi,
I am converting my matlab codes to octave, but I am having troubles with 2 commands below;
first: options=optimset('Algorithm','levenberg-marquardt','Jacobian','off','DerivativeCheck','off','TolX',1e-5,'TolFun',1e-5,'MaxIter',NIter,'display','off');
second: [XOut,ErrorTotal,ErrorPartial] = lsqnonlin('FETProcess_mod2a_Shuoqi',XGuess,XMin,XMax,options,Freq,SMeas,Scale);
From the octave manual, I think there's no "levenberg-marquardt" method in optimset and no lsqnonlin function.
Anyone can show me how to convert the above 2 commands?
Best Regards,
