= EHCA - Eye-head coordination analyzer for the MATLAB programming language =

''Description''

  EHCA is a MATLAB software which was developed to analyze eye-head shifts. It is open-source software that is used for identifying parameters of eye-head coordination. Parameters that are detected are such as eye delay, head offset, eye/head amplitudes and durations. To access the tool from within MATLAB, you have to add the ehca folder to the MATLAB path (File... Set Path...). The tool is started by typing 'ehca' in the MATLAB command window.
