I would like to follow the progress of fminunc is some suitable way. What I can see, there seems to be something called "PlotFcns" in the fminunc.m. Can it be used to plot the progress in some way, like for instance the cost vs nbr iterations, continuously updated during the optimization?
If so, how do I activate the PlotFcns, when calling the fminunc?
If not, is there any other good way to follow the progress? Can I access the final cost in some way aswell?
