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)')
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'])
