How we can use MODEL PREDICTIVE CONTROLLER (MPC) TO GET PREDICTED PARAMETER PLOT?

I am using MPC block given in MATLAB/SIMULINK to control my plant model and I am getting accurate control or can say desired control of the plant but I am not able to see the predicted graph for the parameter which I am controlling. Can anyone help me ? so that I can say that this is my predicted value and this the out put and both can be compared.
