bodemag

Compute the Bode magnitude response of LTI models

Syntax

• bodemag(sys)
  bodemag(sys,{wmin,wmax})
  bodemag(sys,w)
  
  bodemag(sys1,sys2,...,sysN,w)
  bodemag(sys1,'PlotStyle1',...,sysN,'PlotStyleN')
  

Description

bodemag(sys) plots the magnitude of the frequency response of the LTI model SYS (Bode plot without the phase diagram). The frequency range and number of points are chosen automatically.

bodemag(sys,{wmin,wmax}) draws the magnitude plot for frequencies between wmin and wmax (in radians/second).

bodemag(sys,w) uses the user-supplied vector W of frequencies, in
radians/second, at which the frequency response is to be evaluated.

bodemag(sys1,sys2,...,sysN,w) shows the frequency response magnitude of several LTI models sys1,sys2,...,sysN on a single plot. The frequency vector w is optional. You can also specify a color, line style, and marker for each model, as in

•        bodemag(sys1,'r',sys2,'y--',sys3,'gx').
