# gainplot

esboço de magnitude

### Seqüência de Chamamento

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

comments

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