二、部分源代码

function varargout = s2gui(varargin)
% S2GUI M-file for s2gui.fig
%      S2GUI, by itself, creates a new S2GUI or raises the existing
%      singleton*.
%
%      H = S2GUI returns the handle to a new S2GUI or the handle to
%      the existing singleton*.
%
%      S2GUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in S2GUI.M with the given input arguments.
%
%      S2GUI('Property','Value',...) creates a new S2GUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before s2gui_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to s2gui_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
