I used freqz(A,B) to generate the amplitude/phase versus frequency plots of a signal.
Now I want to use only the magnitude plot. How can I extract this plot and display just that. Can I display it as a subplot of a series of plots? How?

Using the debug mode , I find that freqz is calling freqzplot . freqzplot is obsolete and fvtool should be used instead. So to get the same result
b = fir1(80,0.5,kaiser(81,8));
I would replace freqz(b,1) by:

This is my code:
[B,A]= butter(4,.030); Single_HB_30_4= filter(B,A,Single_HB); freqz(B,A)
This gives me 2 plots in one figure. I only want to extract the magnitude plot[1,2,1]. Hod do I do it?
