Scilab Function
gainplot - magnitude plot
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 (in dB) and phases (in degrees) corresponding to frq).
repf : complex matrix. One row for each frequency response.
f_unit : desired frequency unit.
Same as bode but plots only the magnitude.
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'])
