[input]
eegfile : <required> <<file>> EEG-MAT file
active_swt : <optional> <<boolean>> [false] switch for active channel
: true) return only active channels (EEG)
: false) return all the channels (EEG)
ch_type : <optional> [0] | 1 | 2
: 0) all the channels
: 1) only sensor channels (except for external channels)
: 2) only external channels
[output]
