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