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