Method ao/gapfillingoptim

  GAPFILLINGOPTIM fills possible gaps in data.
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
  DESCRIPTION: GAPFILLINGOPTIM minimizes a chi square based on the signal's
               expected PSD. It uses ao/optSubtraction for the small scale
               algorithm, optSubstitution for the large scale algorithm.
 
  CALL:        [aoGapsFilled, plOut, aoP, aoPini, aoWindow, aoWindowShift] = ao.gapfilling(plist)
 
  INPUTS:      ao_data - data segment with the signal to reconstitue
               pl - parameter list
 
  OUTPUTS:     aoGapsFilled  - data segment containing ao_data, with filled data gaps
               plOut         - output plist containing the output of
                               gapfillingoptim
               aoP, aoPini   - final and initial frequency PSD used to weight
                               the optimal problem
               aoWindow      - window used for estmating spectrum
               aoWindowShift - shifted window used for optimizing spectrum

Key Default Value Options Description
gapfillingoptim
ISGAP 'zeros'
  • 'zeros'
  • /No data-object
 Logical ao giving position of gaps. If not
specified, gaps are positionned where there are zeros.
SCALE 'large scale'
  • 'large scale'
  • 'small scale'
 large scale or small scale algorithm
COEFS [] none initial subtracted coefficients, must be a nY*nU double array. If not provided zeros are assumed
WEIGHTINGMETHOD 'residual'
  • 'residual'
  • 'ao'
  • 'pzmodel'
 choose to define a frequency weighting scheme
AOWEIGHT [] none ao to define a frequency weighting scheme (if chosen in 'weightingMethod')
PZMODELWEIGHT [] none pzmodel to define a frequency weighting scheme (if chosen in 'weightingMethod')
LINCOEF 20 none linear coefficient for scaling frequencies in chi2
LOGCOEF 0 none logarithmic coefficient for scaling frequencies in chi2
FITCRITERION 'FTest'
  • 'FTest-NoHfWin'
  • 'FTest'
  • 'chi2'
 criterion to fit the amplitude spectra (increasing quality, increasing time)
ITERMAX 1 none max number of Mex/Exp iterations (only makes sense for "FTest-NoHfWin" fitting criteiron)
NORMCOEFS 9.9999999999999998e-13 none tolerance on inf norm of coefficient update
NORMCRITERION 1.0000000000000001e-05 none tolerance on norm of criterion variation
WIN (WIN='levelledHanning', PSLL=200, LEVELORDER=2) none window to operate FFT, may be a plist/ao
DISPLAY 'off'
  • 'off'
  • 'iter'
  • 'final'
 choose how much to display of the optimizer output
MAXCALL 50000 none maximum number of calls to the criterion function
