Consider the closed-loop system in Figure CP5.11. Develop an m-file to accomplish the following tasks:
(a) Determine the closed-loop transfer function T(s) = Y(s)/R(s),
(b) Plot the closed-loop system response to an impulse input R(s) = 1, a unit step input R(s) = l/s, and a unit ramp input R(s) = l/s2. Use the subplot function to display the three system responses.
