function varargout = MAIN3(varargin)
% MAIN3 MATLAB code for MAIN3.fig
% MAIN3, by itself, creates a new MAIN3 or raises the existing
% singleton*.
%
% H = MAIN3 returns the handle to a new MAIN3 or the handle to
% the existing singleton*.
%
% MAIN3('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in MAIN3.M with the given input arguments.
%
% MAIN3('Property','Value',...) creates a new MAIN3 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before MAIN3_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to MAIN3_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

% See also: GUIDE, GUIDATA, GUIHANDLES
