bode
: plot magnitude and phase of the
frequency response of a linear system.
gainplot
: same as bode but plots only the
magnitude of the frequency response.
nyquist
: plot of imaginary part versus real
part of the frequency response of a linear system.
m_circle
: M-circle plot used with nyquist plot.
chart
: plot the Nichols'chart
black
: plot the Black's diagram (Nichols'chart)
for a linear system.
evans
: plot the Evans root locus for a
linear system.
plzr
: pole-zero plot of the linear system
