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