I want to trace fmincon function in Matlab to get sure it reads the objective function and constraints function from the right files. The problem is when I step in the fmincon function, it goes to other functions that are unnecessary for my tracing aim. I was wonder to ask, does anyone know which lines should I neglect in tracing to only find the part that How to avoid unnecessary functions for tracing of fmincon Matlab call my objective function and constraints function.

Sorry no one got to this one yet. The which command will tell you the location of the file which MATLAB finds first on its search path. If you objective is in a file myObjective.m, then:

which myObjective

will return to you the path of the file MATLAB would use for your objective in your call to fmincon. You can also return all of the files MATLAB finds on its path with the optional flag:

which myObjective -all

If you wish to view your MATLAB path their is an icon under the Environment Section of the Toolbar on your Home Tab. Just note that files in your current folder will always be found ahead of those in the search path.
