 +  <a href=/​reference/​ft_preproc_denoise><​font color=green>​FT_PREPROC_DENOISE</​font></​a>​ performs a regression of the matrix dat onto
 +  refdat, and subtracts the projected data. This is for the 
 +  purpose of removing signals generated by coils during continuous
 +  head motion tracking, for example.
 + 
 +  Use as
 +    [dat] = ft_preproc_denoise(dat,​ refdat, hilbertflag)
 +  where
 +    dat         data matrix (Nchan1 X Ntime)
 +    refdat ​     data matrix (Nchan2 X Ntime)
 +    hilbertflag specifying to regress out the real and imaginary parts of 
 +                  the hilbert transformed signal. Only meaningful for narrow
 +                  band reference data
