二、部分源代码

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