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

  FT_DATATYPE_MVAR describes the FieldTrip MATLAB structure for multi-variate
  autoregressive model data.
 
  The mvar datatype represents multivariate model estimates in the time- or
  in the frequency-domain. This is usually obtained from FT_MVARANALYSIS,
  optionally in combination with FT_FREQANALYSIS.
 
  The following is an example of sensor level MVAR model data in the time domain
 
         dimord: 'chan_chan_lag'     defines how the numeric data should be interpreted
          label: {3x1 cell}          the channel labels
         coeffs: [3x3x5 double]      numeric data (MVAR model coefficients 3 channels x 3 channels x 5 time lags)
       noisecov: [3x3 double]        more numeric data (covariance matrix of the noise residuals 3 channels x 3 channels)
            dof: 500
    fsampleorig: 200
            cfg: [1x1 struct]
 
  The following is an example of sensor-level MVAR model data in the frequency domain
 
         dimord: 'chan_chan_freq'    defines how the numeric data should be interpreted
          label: {3x1 cell}          the channel labels
           freq: [1x101 double]      the frequencies, expressed in Hz
       transfer: [3x3x101 double]
      itransfer: [3x3x101 double]
       noisecov: [3x3 double]
      crsspctrm: [3x3x101 double]
            dof: 500
            cfg: [1x1 struct]
