return coordinates of sensors from EEG-MAT file
[usage]
[sensor, center, result] = vb_load_eeg_sensor(eegfile, active_swt)
[input]
eegfile : <required> <<file>> EEG-MAT file
active_swt : <optional> <<boolean>> [false] switch to filter channel
: true) return only active channels (MEG)
: false) return all the channels (MEG)
: only when mode is 'MEG', this swith is available
[output]
sensor : coordinates of sensors which are loaded from eegfile
: [Nchannel x 3]
center : coordinate of center point
: [1 x 3]
result : <<integer>>
: 0) success
: 1) error - bad eegfile
: 2) error - not be EEG data
