FT_SPECEST_HILBERT

Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_specest_hilbert”.

  FT_SPECEST_HILBERT performs a spectral estimation of data by repeatedly applying a
  bandpass filter and then doing a Hilbert transform.
 
  Use as
    [spectrum,freqoi,timeoi] = ft_specest_hilbert(dat,time,...)
  where
    dat       = matrix of chan*sample
    time      = vector, containing time in seconds for each sample
    spectrum  = matrix of chan*freqoi*timeoi of fourier coefficients
    freqoi    = vector of frequencies in spectrum
    timeoi    = vector of timebins in spectrum
 
  Optional arguments should be specified in key-value pairs and can include
    timeoi    = vector, containing time points of interest (in seconds)
    freqoi    = vector, containing frequencies (in Hz)
    pad       = number, indicating time-length of data to be padded out to in seconds (split over pre/post; used for spectral interpolation, NOT filtering)
    padtype   = string, indicating type of padding to be used (see ft_preproc_padding, default: zero)
    width     = number or vector, width of band-pass surrounding each element of freqoi
    filttype  = string, filter type, 'but' or 'fir' or 'firls'
    filtorder = number or vector, filter order
    filtdir   = string, filter direction,  'twopass', 'onepass' or 'onepass-reverse' 
    verbose   = output progress to console (0 or 1, default 1)
    polyorder = number, the order of the polynomial to fitted to and removed from the data prior to the fourier transform (default = 0 -> remove DC-component)
