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

  FT_FILTER_EVENT does what its name implies
 
  Use as
    event = ft_filter_event(event, ...)
 
  The optional arguments should come in key-value pairs and determine the
  filter characteristics:
    type         = cell-array with strings
    value        = numeric array
    sample       = numeric array
    timestamp    = numeric array
    offset       = numeric array
    duration     = numeric array
    minsample    = value
    maxsample    = value
    minduration  = value
    maxduration  = value
    mintimestamp = value
    maxtimestamp = value
    minnumber    = value, applies only if event.number is present
    maxnmumber   = value, applies only if event.number is present
