function varargout = GUI2(varargin)
% GUI2 MATLAB code for GUI2.fig
% GUI2, by itself, creates a new GUI2 or raises the existing
% singleton*.
%
% H = GUI2 returns the handle to a new GUI2 or the handle to
% the existing singleton*.
%
% GUI2('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in GUI2.M with the given input arguments.
%
% GUI2('Property','Value',...) creates a new GUI2 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before GUI2_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to GUI2_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
