How can I save the output parameters for each step using lsqnonlin function?

I am performing a nonlinear least square estimation of some parameters of a rational function to fit some experimental data, and I would like to save the parameters (x) obtained for each optimization step (and not just the final values). What can I do?

Best regards,

Write an output function to save the values, either to a workspace variable or to a file. For syntax details, see Output Function and Plot Function Syntax.
