Method ao/polyfitSpectrum


  POLYFITSPECTRUM does a polynomial fit to the log of the input spectrum.
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
  DESCRIPTION: POLYFITSPECTRUM does a polynomial fit to the log of the
               input spectrum.
  
  The method returns the fitted model spectrum as an fsdata AO, evaluated
  at the frequencies specified. In the procinfo of the output objects
  contains the fit as a pest object.
 
  CALL:        bs = polyfitSpectrum(a1,a2,a3,...,pl)
               bs = polyfitSpectrum(as,pl)
               bs = polyfitSpectrum.psd(pl)
 
  INPUTS:      aN   - input fsdata analysis objects
               as   - input fsdata analysis objects array
               pl   - input parameter list
 
  OUTPUTS:     bs   - array of analysis objects, one for each input

Key Default Value Options Description
FFIT [] none The frequency range on which to split the input data for fitting in the form [f1 f2]. If empty, the full input spectrum will be fit.
FOUT [] none The frequency range on which to evauate the fit. If empty, the full range of the input spectrum will be used.
ORDERS [] none The orders of polynomial to fit to the spectrum.
PLOT FITS 0
  • 0
  • 1
Set to true to produce plots of the fits.
