2 部分代码

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