function varargout = exp3(varargin)
% EXP3 M-file for exp3.fig
% EXP3, by itself, creates a new EXP3 or raises the existing
% singleton*.
%
% H = EXP3 returns the handle to a new EXP3 or the handle to
% the existing singleton*.
%
% EXP3('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in EXP3.M with the given input arguments.
%
% EXP3('Property','Value',...) creates a new EXP3 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before exp3_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to exp3_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
