Question: Consider the block diagram in Figure.
(a) Use an m-file to reduce the block diagram in Figure, and compute the closed-loop transfer function.
(b) Generate a pole-zero map of the closed-loop transfer function in graphical form using the pzmap function.
(c) Determine explicitly the poles and zeros of the closed-loop transfer function using the pole and zero functions and correlate the results with the pole-zero map in part (b).
