2 Y-axes in the same figure

[Eduardo J. Adam]

Dear friends,
I need to draw two axes in the same figure as shown below.
The
 example is a tipical bode plot but, I don't want to use subplot 
command. In consequence, I need one axis on the rigth and another on the
 left.

clear all, clf
K=1; n=K; d=[1 0.2 1 0];
gs=tf(n,d);
[mag_gs,pha_gs,w]=bode(gs);
mag_gs_db=20*log(mag_gs);

I have no idea how this is done.
