Estimate the frequency response of the specified portion of the model. The result is a
frequency-response model containing responses at each of the frequencies specified in
the sinestream signal.
sysest = frestimate(model,op,io,input);
size(sysest)
FRD model with 1 outputs, 1 inputs, and 30 frequency points.
Examine the measured frequency response.
