nlinfit - iteration limit exceeded error
显示 更早的评论
Hi All,
Im trying to do nonlinear regression using nlinfit, and I keep getting the warning "iteration limit exceeded".
I have 6 coefficients that Im trying to estimate using nlinfit. Is the number of coefficients the reason that im getting this warning? Is 6 coefficients too much to estimate within the limited number of iterations?
I changed the initial values of all the coefficients closer to the expected answer, but still this error keeps coming up.
Please help me understand this if you can. Thank you very much.

Probably your termination tolerance is too small for the data you're throwing at it.
Play with the options 'MaxIter', 'TolFun', and 'TolX'.
