gainplot Scilab Function

gainplot - magnitude plot

Calling Sequence

gainplot(sl,fmin,fmax [,step] [,comments] )

gainplot(frq,db,phi [,comments])

gainplot(frq, repf [,comments])

Parameters

sl : list (syslin SIMO linear system).
fmin,fmax : real scalars (frequency interval).
step : real (discretization step (logarithmic scale))
comments : string
frq : matrix (row by row frequencies)
db,phi : matrices (magnitudes and phases corresponding to frq)
repf : complex matrix. One row for each frequency response.

Description

Same as Bode but plots only the magnitude.

Examples


s=poly(0,'s')
h=syslin('c',(s^2+2*0.9*10*s+100)/(s^2+2*0.3*10.1*s+102.01))
gainplot(h,0.01,100,'(s^2+2*0.9*10*s+100)/(s^2+2*0.3*10.1*s+102.01)')
clf()
h1=h*syslin('c',(s^2+2*0.1*15.1*s+228.01)/(s^2+2*0.9*15*s+225))
gainplot([h1;h],0.01,100,['h1';'h'])
