二、部分源代码

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