Hello,
I am using a Non linear MPC formulation for my problem, but I would like to check the results of fmincon at each iteration or generally see the "under the hood" options of the Non linear MPC solver.
How could I do that?

The options OutputFcn and PlotFcn (which you specify using optimoptions) allows you see what happens in each iteration online.
I for exmaple once written a custom OutputFcn to save each iteration data in a log file.
Please see https://www.mathworks.com/help/optim/ug/output-functions.html for details.
