 +  <a href=/​reference/​ft_specest_mtmfft><​font color=green>​FT_SPECEST_MTMFFT</​font></​a>​ computes a fast Fourier transform using multitapering with
 +  multiple tapers from the DPSS sequence or using a variety of single tapers.
 + 
 +  Use as
 +    [spectrum,​ntaper,​freqoi] = ft_specest_mtmfft(dat,​time...)
 +  where
 +    dat        = matrix of chan*sample
 +    time       = vector, containing time in seconds for each sample
 +    spectrum ​  = matrix of taper*chan*freqoi of fourier coefficients
 +    ntaper ​    = vector containing number of tapers per element of freqoi
 +    freqoi ​    = vector of frequencies 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, total length of data after zero padding (in seconds)
 +    padtype ​   = string, indicating type of padding to be used (see ft_preproc_padding,​ default: zero)
 +    freqoi ​    = vector, containing frequencies of interest
 +    tapsmofrq ​ = 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'​ (default) or '​chan_time_freqtap'​ for memory efficiency (only when use variable number slepian tapers)
 +    polyorder ​ = number, the order of the polynomial to fitted to and removed from the data prior to the fourier transform (default = 0 -&gt; remove DC-component)
 +    taperopt ​  = additional taper options to be used in the WINDOW function, see WINDOW
 +    verbose ​   = output progress to console (0 or 1, default 1)
