How to measure time that fmincon takes to extract one solution from a NMPC running in Simulink

I am running a Non-linear MPC at Simulink and I would like to know if it is possible to measure the computational time it takes for the fmincon to generate a solution for the controller per simulation time step. I have seen commands like tic/toc, cputime etc, but my issue is that I don't know a way that I could go "under the hood" and put these commands before and after fmincon.
If somebody knows, could you please help me?

By building your nonlinear controller, you need to create the object nlopc, when you excute your model, call this function:
t= timeit(nlopc(nx, ny, nu))
where nx, ny, nu are the numbers of states variables, outputes, and inputes of your controller.
