03 Jun 2009 LMFnlsq - Solution of nonlinear least squares Efficient and stable Levenberg-Marquard-Fletcher method for solving of nonlinear equations Author: Miroslav Balda

i try to run the Example Rosenbrock's function ( SQP)with "xy" in the output arguments ..but it not work ...it shows xy =[ ] empty matrix...can any body clear this to me?...

function ros = rosen(x)
d = sqrt(x(1)^2+x(2)^2)-1.5;
r=1.5;
ros = [ 10*(x(2)-x(1)^2) % first part, f1(x)
1-x(1) % second part, f2(x)
(d>0)*d*1000 ];


x0=[-1.9,2];
>> options=LMFnlsq;
>> [x,ssq,cnt,nfJ,XY] = LMFnlsq('rosen',x0,options)
