Write a program in MATLAB that will do the following:

a. Allow a value of gain, K, to be entered from the keyboard

b. Display the closed-loop magnitude and phase frequency response plots of a unity feedback system with an open loop transfer function, KG(s)

c. Calculate and display the peak magnitude, frequency of the peak magnitude, and bandwidth for the closed-loop frequency response and the entered value of K Test your program on the system of Figure P10.5 for K = 50.
