Illustration of Frequency Response (magnitude and phase response)

Hi,

I have a list of frequency values (10hz to 1Mhz), output voltages and phase difference angles. But I don't know how I can go about plotting the frequency response

Wouldn't it just be to plot() the two variables vs the frequency vector?

I actually have 3 list of values: Frequency, Output Voltages and Phase Difference (°). I'm basically confused on whether I should use bode or plot

if you wnat to plot them yourself, then use plot(), or semilogx() or whatever plotting function meets your needs.

Or you can define and frd object and then use Control System Toolbox functions, like bode(), to do the lifting
