fselect
Select frequency points or range in FRD model
Syntax
subsys = fselect(sys,fmin,fmax)
subsys = fselect(sys,index)
Description
subsys = fselect(sys,fmin,fmax) takes an FRD model sys and selects the
   portion of the frequency response between the frequencies fmin and
    fmax. The selected range [fmin,fmax] should be expressed
   in the FRD model units. For an IDFRD model, the SpectrumData,
    CovarianceData and NoiseCovariance values, if non-empty,
   are also selected in the chosen range. 
subsys = fselect(sys,index) selects the frequency points specified by
   the vector of indices index. The resulting frequency grid is 
sys.Frequency(index)
