Plotting a bode diagram without transfer function, using only magnitude and phase and frequency

I have 15x specified frequencies and for each frequency I have the magnitude in dB and the phase. I don't have the transfer function but I am curious if its possible to plot a bode diagram using those data.

Phase is probably not completely correct because I calculated it using seconds not ms.

w = [0.01 0.02 0.05 0.1 0.2 0.5 1 2 5 10 20 50 100 200 500]

Mag = [11.1 12.4 11.2 10.3 9.7 8.7 7.1 4.8 2.5 1.6 0.7 0.17 0.08 0.02 0.003]

Mag(dB) = [20.9 21.9 21.1 20.2 19.8 18.8 16.9 13.7 7.9 4.4 -2.9 -15.4 -22.6 -34.3 -49.4]

Phase = [10.5 5.9 5.0 1.5 10.2 40.8 47.6 81.5 108 165.6 230.4 324 543.6 925.9 2008.8]

hello

by definition, plotting a Bode diagram requires somehow to have frequency / magnitude and phase

As you have those data, you can surely plot them. You can also use it for feedback control - as soon as it involves only plotting the open loop and closed loop tf

You can use the data you have to make an frd model:

doc frd

Once you have the frd model you can make the bode plot using the bode() command as for any other dynamic system model.
