How to store every iteration points of GA in m-file?

Hello Sir, I am new to MATLAB and currently I am performing GA to get nonlinear constrained global minimization.I wrote the code and its running perfectly. But I want to save all Iteration points on mat files so that i can compare between them. I know a custom output function can serve the purpose but i can't do it. So, plz provide me some documentation or code so that i can do the desirable.

thank you,

seems to be the output argument you need. I don't have the optimisation toolbox myself, but that appears to store the output from each generation of the algorithm.

If you wish to save that to a mat file or just use it straight away in your code is up to you, but I don't think you need to do anything fancy for saving per iteration, just get all iteration outputs at once and use those.
