二、部分源代码

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