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')

在 MATLAB Online 中打开

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)

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
