 +  <a href=/​reference/​ft_freqanalysis_mvar><​font color=green>​FT_FREQANALYSIS_MVAR</​font></​a>​ performs frequency analysis on
 +  mvar data, by fourier transformation of the coefficients. The output
 +  contains cross-spectral density, spectral transfer matrix, and the
 +  covariance of the innovation noise. The dimord = '​chan_chan(_freq)(_time)
 + 
 +  The function is stand-alone,​ but is typically called through
 +  <a href=/​reference/​ft_freqanalysis><​font color=green>​FT_FREQANALYSIS</​font></​a>,​ specifying cfg.method = '​mvar'​.
 + 
 +  Use as
 +    [freq] = ft_freqanalysis(cfg,​ data), with cfg.method = '​mvar'​
 + 
 +  or
 + 
 +    [freq] = ft_freqanalysis_mvar(cfg,​ data)
 + 
 +  The input data structure should be a data structure created by
 +  <a href=/​reference/​ft_mvaranalysis><​font color=green>​FT_MVARANALYSIS</​font></​a>,​ i.e. a data-structure of type '​mvar'​.
 + 
 +  The configuration can contain:
 +    cfg.foi = vector with the frequencies at which the spectral quantities
 +                are estimated (in Hz). Default: 0:1:Nyquist
 +    cfg.feedback = '​none',​ or any of the methods supported by <a href=/​reference/​ft_progress><​font color=green>​FT_PROGRESS</​font></​a>,​
 +                     for providing feedback to the user in the command
 +                     ​window.
 + 
 +  To facilitate data-handling and distributed computing you can use
 +    cfg.inputfile ​  ​= ​ ...
 +    cfg.outputfile ​ =  ...
 +  If you specify one of these (or both) the input data will be read from a *.mat
 +  file on disk and/or the output data will be written to a *.mat file. These mat
 +  files should contain only a single variable, corresponding with the
 +  input/​output structure.
