I'm using fminsearch to find parameters (para) that minimize the objective function. To exaplain, I have the following line that calls 'myfunction' that calculates the objective function:
[parahat,fval,exitflag] = fminsearch(@(para)myfunction(para), para0, X,opts);
where 'para0' contains initial values, X are some input arguments, and 'parahat' containes the estimated parameters. Here, I'm wondering if there's a way to save some results from 'myfunction' produced in the process of getting to the objective function. myfunction is written as :
function [dist] = myfunction(para, X)
and in reaching 'dist' which is to be minimized, the function calculates some values, let's say Y and Z.
Is there a way to report Y and Z calculated based on 'parahat' (so the last Y and Z in the process of searching for the minimum) along with 'parahat' and 'fval'?
Thank you very much for your help in advance.

Hi Ara,
Please refer to the documentation of assignin function to create variables in a specific workspace when the code is running in a different workspace.
Hope this helps
