I want to change the ylabels on a Bode plot. As you know with the command bode there are two plots, one for magnitude and one for phase. But when you write:
ylabel('TheLabel')
Only the word "Phase" is changed to "TheLabel", but the word "Magnitude" is unchanged.
How do you write in order to change both the word "Magnitude" and the word "Phase"?

bode(tf(1,1:2)) % Example
axes=findobj('type','axes')
h_magnitude=get(axes(2),'YLabel')
h_phase=get(axes(1),'YLabel')
set(h_magnitude,'String','NewMagnitude')
set(h_phase,'String','NewPhase')

How do you write then? Can you post the code please?

s=zpk('s');
p1=1;
Hs=1/(1+s/p1);
bode(Hs, {0.1,10})
axes=findobj('type','axes')
h_magnitude=get(axes(2),'YLabel')
h_phase=get(axes(1),'YLabel')
set(h_magnitude,'String','NewMagnitude')
set(h_phase,'String','NewPhase')
