Id like to have absolute gain as it generates the plot instead of having to do it manually. I was able to change frequency from rad to hz. not sure about the db to absolute. Thank you

Hi,
Is it something that can be done like this?
h = gcr
setoptions(h,'FreqUnits','Hz')

Ran in:
H = tf([1 0.1 7.5],[1 0.12 9 0 0]);
[mag,phase,wout] = bode(H);
subplot(211); plot(wout, squeeze(mag(1,1,:)))
subplot(212); plot(wout, squeeze(phase(1,1,:)))
figure;
bode(H)

HI this solution works as well but is there an option to do it this way
h = gcr
setoptions(h,'FreqUnits','Hz')
etc

No (unless you write your own class for creating the figure and set your own object property). Why do you need to do it that way?

It is a property setting on the figure, I can easily change it manually. I did the same thing for the frequency from rad to hz. im sure there is a way to do the same from db to absolute gain

Can be done if using bodeplot instead of bode
H = tf([1 0.1 7.5],[1 0.12 9 0 0]);
h = bodeplot(H);
setoptions(h,'MagUnits','abs','FreqUnits','Hz')
