magnitude plot
gainplot(sl, fmin, fmax) gainplot(sl, fmin, fmax, step) gainplot(frq, db, phi) gainplot(frq, repf) gainplot(.., comments)
A siso or simo linear dynamical system, in state space, transfer function or zpk representations, in continuous or discrete time.
real scalars (frequency interval).
real (discretization step (logarithmic scale))
string
matrix (row by row frequencies)
matrices (magnitudes and phases corresponding to
frq
)
complex matrix. One row for each frequency response.
Same as bode but plots only the magnitude.
