bode plot from measured data

hello all, I have some measured data ,current as input and voltage as output with a sampling freq of 10e3.

voltage and current are saved differently in two vectors. during the test for every try we changed frequency in current. for a range of 150-2450 Hz. now I have for current 24 vectors and every vector is related to only one specefic frequency and I also have 24 vectors for the voltage related to the current. now I want to plot bode diagram using tfestimate but my problem is that tfestimate give me 24 seperate answers.

how can I get only one tf for the frequency range between 150-2450 Hz.

thx

You seem to have gone the long way round to collect frequency-domain data from your system.

It is difficult to suggest a specific approach, however finding some way to determine the amplitude and phase characteristics at each frequency would likely be the first step. Then use the procedures in Frequency-Domain Data in iddata to create your data object.

A simpler way would likely be to use the same sampling frequency, and record the respoinse of your system to an impulse, if you can do that. Then use that time-domain matrix, or the fft of it as a frequency-domain matrix to use with iddata (or idfrd).
