I have two figures
figure(1)
margin(x)
figure(2)
margin(y)
i want generate a figure which contain these two figures( not subplot).
that show like
bode(x,y)
but i want to have "margin" information.

Say again?
Not subplot:
Ok, so two traces?

[aX,fX] = margin(x);
[aY,fY] = margin(y);
plot(fX,aX,fY,aY);

If you have gain or phase margin info output, how do you get it now?

That can show any traces....
margin() %that can show gain & margin info in bode diagram

Sorry I still have no idea what you want.
Do you want code to calculate gain & phase margin?
If so, what is the two plot thing?

Anyone else help?
