Interpolate FRD model
isys = interp(sys,freqs)
isys = interp(sys,freqs) interpolates the frequency response data
contained in the FRD model
sys at the frequencies
interp, which is an overloaded version of the MATLAB® function
interp, uses linear interpolation and returns an FRD
isys containing the interpolated data at the new frequencies
sys is an IDFRD model, the noise spectrum, if non-empty, is also interpolated. The
response and noise covariance data, if available, are also interpolated.
You should express the frequency values
freqs in the same units as
sys.frequency. The frequency values must lie between the smallest and largest
frequency points in
sys (extrapolation is not supported).
