| 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('Property','Value',...) creates a new GUITEST using the
% given property value pairs. Unrecognized properties are passed via
% varargin to GuiTest_OpeningFcn. This calling syntax produces a
% warning when there is an existing singleton*.
%
% GUITEST('CALLBACK') and GUITEST('CALLBACK',hObject,...) call the
% local function named CALLBACK in GUITEST.M with the given input
% arguments.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
