# gainplot

esboço de magnitude

### Seqüência de Chamamento

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

### Parâmetros

sl

lista (sistema linear syslin SIMO).

fmin,fmax

escalares reais (intervalo de freqüência).

step

real (passo de discretização (escala logarítmica))

string

frq

matriz (freqüências linha por linha)

db,phi

matrizes (magnitudes e fases correspondentes a frq)

repf

matriz de complexos. Uma linha para cada resposta de freqüência.

### Descrição

É o mesmo que Bode, mas esboça apenas a magnitude.

### Exemplos

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,..
["$\frac{s^2+18 s+100}{s^2+6.06 s+102.1}$";
"$\frac{s^2+3.02 s+228.01}{s^2+27 s+225}$"])
