Uncertainty

Hi

How can we get uncertainty in parameters when we use fminsearch for fitting? Is there any routine to compute this by having the residuals?

Thanks for any help, Nick

Hi, I think since fminsearch is a derivativ-free method, it cannot calculate the uncertainty of answer. You can use lsqcruvefit or lsqnonlin depending on the structure of xdata and ydata.
