Change ylabels on Bode plot

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')

Ok, your code works on it's own, but not when I try to incorporate it in my own. I wrote

s=zpk('s');
p1=1;
Hs=1/(1+s/p1);
bode(Hs, {0.1,10})

When I try to combine it with your code I get the following error message:

Error using InputOutputModel/subsref (line 43)
Subscript no. 2 is out of range.

Error in Rellpol (line 21)
bode(Hs(1,1:2))  % Example

How should I write in order to make it work together with my code? Please note that I want to be able to set the width of the x-axis manually, so that's why I wrote this in bold:

bode(Hs {0.1,10})

How should I write to do all this together?

This works fine with me

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')
