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

  FT_SPECEST_MTMCONVOL performs wavelet convolution in the time domain by
  multiplication in the frequency domain.
  Use as
    [spectrum,ntaper,freqoi,timeoi] = ft_specest_mtmconvol(dat,time,...)
  where input
    dat       = matrix of chan*sample
    time      = vector, containing time in seconds for each sample
  and output
    spectrum  = matrix of ntaper*chan*freqoi*timeoi of fourier coefficients
    ntaper    = vector containing the number of tapers per freqoi
    freqoi    = vector of frequencies in spectrum
    timeoi    = vector of timebins in spectrum
  Optional arguments should be specified in key-value pairs and can include
    taper     = 'dpss', 'hanning' or many others, see WINDOW (default = 'dpss')
    pad       = number, indicating time-length of data to be padded out to in seconds
    padtype   = string, indicating type of padding to be used (see ft_preproc_padding, default: zero)
    timeoi    = vector, containing time points of interest (in seconds)
    timwin    = vector, containing length of time windows (in seconds)
    freqoi    = vector, containing frequencies (in Hz)
    tapsmofrq = number, the amount of spectral smoothing through multi-tapering. Note: 4 Hz smoothing means plus-minus 4 Hz, i.e. a 8 Hz smoothing box
    dimord    = 'tap_chan_freq_time' (default) or 'chan_time_freqtap' for memory efficiency
    verbose   = output progress to console (0 or 1, default 1)
    taperopt  = additional taper options to be used in the WINDOW function, see WINDOW
    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)
