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

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. |
