FieldTrip

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

  function [FM, xf] = ft_preproc_online_filter_apply(FM, x)
 
  Passes signal x (channels times samples) through the filter,
  returns updated filter model (delay states!) and filtered signal.
