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

  FT_APPENDFREQ concatenates multiple frequency or time-frequency data
  structures that have been processed seperately. If the input data
  structures contain different channels, it will be concatenated along the
  channel direction. If the channels are identical in the input data
  structures, the data will be concatenated along the repetition dimension.
 
  Use as
    combined = ft_appendfreq(cfg, freq1, freq2, ...)
