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