[mag,phase,w] = nichols(sys)

[mag,phase] = nichols(sys,w)

return the magnitude and phase (in degrees) of the frequency response at the

w (in rad/sec). The outputs mag and phase are 3-D arrays similar to

those produced by

bode (see the bode reference page). They have dimensions

Example Plot the Nichols response of the system

num = [-4 48 -18 250 600];

den = [1 30 282 525 60];

H = tf(num,den)
