//功能:
/*些程序用于实现将Matlab窗口嵌入到C#的窗口中,并实现随主窗口的
 * 大小改变而改变,同时Matlab原有的工具箱仍然保留
 */

//原理:
/*先在matlab里画一个特别小的窗口, 小到看不见, 因为如果要是用figure('Visible','off')
 * 的窗口后面用findwindow()找到matlab图形窗口的过程就会失败. 找到图形窗口之后,就可以设置其父窗口
 */

//实现技术要点:
/*
 * 1.利用Matlab抽作一个显示图形的Dll,以供在C#中调用,绘制图形
 * 2.在C#中导入该DLL(本例中为ShowPicture)
 * 3.导入Matlab For .Net引擎(本机路径:D:\Program Files\MATLAB\R2007a\toolbox\dotnetbuilder\bin\win32\v2.0\MWArray.dll)
 * 4.由于要用到一些Win32 API,事先声明一些API函数(在本例中为DotNetWin32所封装了一些必须的API函数)
 */

//存在问题
/*1.应该在Matlab 显示图形DLL中,将图形窗口初始化一个特别小的窗口, 小到看不见
 * 2.应该当两个窗口都显示出来再去FindWindow
 *
