Use MATLAB to draw the bode plot of closed-loop transfer function

A freelancer with understanding of power electronics, control system engineering and proficient with MATLAB.
I'll provide a buck converter circuit and i need you to find:

1) get bode plot of loop gain T(s) when Gc(s) = 1, find out crossover frequency fc and phase
margin ?௠. (Tips: use MATLAB to draw the bode plot for T(s))

(ps: i'll Provide buck converter system specifications)
