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