Hi, Balda
Thanks for your reply. My curve fitting prblem is to calibrate the model like this:
Y(i)=A+B*(Tc-t(i))^m+C1*cos(w*ln(Tc-t(i))) +C2*sin(w*ln(Tc-t(i)))
The parameters to be estimate is A,B,C1,C2,m,w,Tc,
and the Constraints is:
B<0, |C1|<1, |C2|<1, Tc>max(t(i)), 0.1<m<0.9, 6<w<13, So how to write the L-M expression using the LMFnlsq2.m ?

Can the function do Curve fiting with constraints?
How?
