WebQ = 2.3; R = 1; Use the kalman command to design the filter. [kalmf,L,~,Mx,Z] = kalman (sys,Q,R); This command designs the Kalman filter, kalmf, a state-space model that implements the time-update and measurement-update equations. The filter inputs are the plant input u and the noisy plant output y.
