I have a discrete-time state space model. x(:,k+1) = Ax(k) + Bu(k);
I have written MATLAB code to obtain perfect tracking of reference r using LQI. I used the following line x(:,k+1) = Ax(k) + B*(-K*x) + Be*r(k);
Now, i need the control input trajectory u(k) for further analysis. Please, how do I do this?

hi, I hope, it is still relevant: to compute u(k) = K*x(k)
