I'm trying to do this using output functions, but the form of the function seems very restrictive, and it doesn't allow me to store the intermediate values in some pre-allocated matrix. All I can do is print the output, which means everything from that point on must be done manually... any help?
lsqcurvefit.m ... how to find intermediate steps?

Hi
I'm fitting using lsqcurvefit and the OUTPUT structure tells me there are 4 steps with 20 function evaluations before the stopping criteria is reached. Is there any way to find the parameter values at each of these steps?
My goal is to plot each fit to demonstrate the improvement between model and data.
Regards, Michael

You could have your objective function print to a text file explicitly or keep a persistent variable around that stores the intermediate steps.
