% This is the main function of the Eyelink toolbox

% For general advice, try:
help Eyelink

% For a more detailed explanation of any Eyelink function, just add a question mark “?”.
% E.g. for ‘Initialize’, try either of these equivalent forms:
Eyelink Initialize?

% If you think you’ve found a bug, please report it
on the forum, see: http://psychtoolbox.org/

% EyelinkToolbox version for the OpenGL PsychToolbox
% The EyelinkToolbox was developed by:

Frans Cornelissen  
Enno Peters  
John Palmer  
Chris Burns  
Mario Kleiner  
Erik Flister  
Nuha Jabakhanji  

The EyelinkToolbox can be used to ceate eye-movement experiments and      control the SR-Research Eyelink� gazetrackers      (http://www.eyelinkinfo.com/) from within Matlab.      It is incorporated into the PsychToolbox (http://www.psychtoolbox.org/).      and uses the functions provided by the PsychToolBox for graphics and sound.  

For a complete list of available functions type “Eyelink” in the
Matlab command window. For an explanation of any particular Eyelink
function just add a question mark “?” after a command.
E.g. for ‘Initialize’, try either of these equivalent forms:
Eyelink initialize?

[optional arguments]:  
Brackets in the function list, e.g. [remport], indicate optional      arguments, not matrices. Optional arguments must be in order, without      omitting earlier ones.  
If you need examples to get you started, check out the EyelinkDemos      folder.
