I've been using Matlab to try to analyze data I received that contains the impedance and frequency of some material which varies depending on the voltage applied. The data that was captured contains the amplitude, phase, and frequency of the voltage applied.
Using this data, a function was created to find the impedance and I would like to graph this data. Can the built in bode and nyquist functions use array data to create a plot? I've just been manually creating bode plots using frequency by 20*log10(magnitude) but I would like to use the bode function. Using 'help bode', I believe that a transfer function is needed to use the bode() function, so it seems that I need to manually plot the points instead of use bode().
