.TH gainplot 1 "April 1993" "Scilab Group" "Scilab Function"
.so ../sci.an
.SH NAME
gainplot - magnitude plot
.SH CALLING SEQUENCE
.nf
gainplot(sl,fmin,fmax [,step] [,comments] )
gainplot(frq,db,phi [,comments])
gainplot(frq, repf [,comments])
.fi
.SH PARAMETERS
.TP 10
sl
: list (\fVsyslin\fR SIMO linear system).
.TP
fmin,fmax
: real scalars (frequency interval).
.TP
step
: real (discretization step (logarithmic scale))
.TP
comments
: string
.TP
frq
: matrix (row by row frequencies)
.TP
db,phi
: matrices (magnitudes and phases corresponding to \fVfrq\fR)
.TP
repf
: complex matrix. One row for each frequency response.
.SH DESCRIPTION
Same as Bode but plots only the magnitude.
.SH EXAMPLE
.nf
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)')
xbasc()
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'])
