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.
