Hello Matlab experts here,

I have a general question: When one uses Matlab functions for minimization (eg, fminsearch, fminunc, lsqnonlin, etc.), is there any way to store the information of the path of minimization? (that is, the points visited by the algorithm from the starting positions to the terminating positions)

I searched for the option without finding it.

Thank you all in advance!

You can use an output function to record the points. For examples, see
