function varargout = Snake(varargin) % SNAKE M-file for Snake.fig % SNAKE, by itself, creates a new SNAKE or raises the existing % singleton*. % % H = SNAKE returns the handle to a new SNAKE or the handle to % the existing singleton*. % % SNAKE('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in SNAKE.M with the given input arguments. % % SNAKE('Property','Value',...) creates a new SNAKE or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before Snake_OpeningFunction gets called. An % unrecognized property name or invalid value makes property application % stop.
