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

  FT_SPECEST_NEUVAR computes a time-domain estimation of overall signal 
  power, having compensated for the 1/f distribution of spectral content.
 
  Use as
    [spectrum,ntaper,freqoi] = ft_specest_neuvar(dat,time...)
  where
    dat        = matrix of chan*sample
    time       = vector, containing time in seconds for each sample
    neuvar     = matrix of chan*neuvar
 
  Optional arguments should be specified in key-value pairs and can include
    order      = number, the order of differentation for compensating for the 1/f (default: 1)
    pad        = number, total length of data after zero padding (in seconds)
    padtype    = string, indicating type of padding to be used (see ft_preproc_padding, default: 0)
    verbose    = output progress to console (0 or 1, default 1)
