How can i obtain the angular frequency from the bode plot having the magnitude?

i have the Bode plot, and for a certain Magnitude(dB) I want to get the angular frequecy. how do i get it?

If you already have the bode plot then you can click on the plot with the datacursor on the toolbar and it will show you the mag and the phase (which is the angular frequency omega) Alternatively you can call the same bode function as follows:

[mag,ph,w,sdmag,sdphase] = bode(sys,w); and it will return the mag and the corresponding phase or omega in the variable ph.
