% TEST14_20130502 M-file for test14_20130502.fig
% TEST14_20130502, by itself, creates a new TEST14_20130502 or raises the existing
% singleton*.
%
% H = TEST14_20130502 returns the handle to a new TEST14_20130502 or the handle to
% the existing singleton*.
%
% TEST14_20130502('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in TEST14_20130502.M with the given input arguments.
%
% TEST14_20130502('Property','Value',...) creates a new TEST14_20130502 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before test14_20130502_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to test14_20130502_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
