Construct an options structure that includes PlotFcn and give an option value of @optimplotfval . The options structure can be constructed using the new optimoptions or the older optimset .
The options structure must be passed as the 10th parameter to fmincon(), so if you do not need some of the parameters, pass [] in their place.

Hello Roberson, based on your instructions i established this snippet of code that works perfectly :
>> options = optimset('PlotFcns',@optimplotfval);
>> [y,fval] = fmincon(f,x0,[],[],[],[],[0,0],[1,1],[],options);
what do you think?
