function varargout = QJgj2(varargin)

%QJGJ2 M-file for QJgj2.fig
%      QJGJ2, by itself, creates a new QJGJ2 or raises the existing
%      singleton*.
%
%      H = QJGJ2 returns the handle to a new QJGJ2 or the handle to
%      the existing singleton*.
%
%      QJGJ2('Property','Value',...) creates a new QJGJ2 using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to QJgj2_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      QJGJ2('CALLBACK') and QJGJ2('CALLBACK',hObject,...) call the
%      local function named CALLBACK in QJGJ2.M with the given input
%      arguments.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
