function varargout = daunxujian1(varargin)
% DAUNXUJIAN1 MATLAB code for daunxujian1.fig
% DAUNXUJIAN1, by itself, creates a new DAUNXUJIAN1 or raises the existing
% singleton*.
%
% H = DAUNXUJIAN1 returns the handle to a new DAUNXUJIAN1 or the handle to
% the existing singleton*.
%
% DAUNXUJIAN1('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in DAUNXUJIAN1.M with the given input arguments.
%
% DAUNXUJIAN1('Property','Value',...) creates a new DAUNXUJIAN1 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before daunxujian1_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to daunxujian1_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
