I would like to get bode plot from FFT data. How do I convert the data obtained(complex values) so that it can be used by the 'bode' function in matlab.
You need to create an frd object.
here is example code from doc page.
% generate a frequency vector and response data
freq = logspace(1,2);
resp = .05*(freq).*exp(i*2*freq);
% Create a FRD model
sys = frd(resp,freq);
Now simply do

Thanks Arkadiy for the reply.
However, I am unable to understand how to make frd data from fft data. I got lets say ,following data points after doing fft [2+2j,1-3j,4, 5+4j]. How do i convert this into frd.
freq= % enter the frequency values at which the corresponding fft
% values are obtained
