 +  <a href=/​reference/​ft_preproc_hilbert><​font color=green>​FT_PREPROC_HILBERT</​font></​a>​ computes the Hilbert transpose of the data and optionally
 +  performs post-processing on the complex representation,​ e.g. the absolute
 +  value of the Hilbert transform of a band-pass filtered signal corresponds
 +  with the amplitude envelope.
 + 
 +  Use as
 +    [dat] = ft_preproc_hilbert(dat,​ option)
 +  where
 +    dat        data matrix (Nchans X Ntime)
 +    option ​    ​string that determines whether and how the Hilbert transform
 +               ​should be post-processed,​ can be
 +                 '​abs'​
 +                 '​complex'​
 +                 '​real'​
 +                 '​imag'​
 +                 '​absreal'​
 +                 '​absimag'​
 +                 '​angle'​
 + 
 +  The default is to return the absolute value of the Hilbert transform.
