H(s)G(s) = 30(s+2)/(s^3+7s^2+12s)

In MATLAB, Use the function margin to plot log-magnitude, phase, gain margin, phase margin. Do not use the function bode.

I graphed it using margin, but how do I just get the phase? I got the gain margin, phase margin, and the cross over frequencies. Thanks

9. The purpose of this problem is to use MATLAB to compute the magnitude, phase, and total energy of a Fourier transform. a) Develop a MATLAB routine to plot the magnitude and phase of a given Fourier transform H(jω). The input part of your program will, of course, require that you specify the particular H(jω) of interest, but, once this is done, your program should not depend on the Fourier transform specified. You will need to select an appropriate range...
