function varargout = Main(varargin) % MAIN MATLAB code for Main.fig % MAIN, by itself, creates a new MAIN or raises the existing % singleton*. % % H = MAIN returns the handle to a new MAIN or the handle to % the existing singleton*. % % MAIN('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in MAIN.M with the given input arguments. % % MAIN('Property','Value',...) creates a new MAIN or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before Main_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to Main_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
