function varargout = gui02(varargin)
% GUI02 MATLAB code for gui02.fig
%      GUI02, by itself, creates a new GUI02 or raises the existing
%      singleton*.
%
%      H = GUI02 returns the handle to a new GUI02 or the handle to
%      the existing singleton*.
%
%      GUI02('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in GUI02.M with the given input arguments.
%
%      GUI02('Property','Value',...) creates a new GUI02 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before gui02_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to gui02_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
