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'])
