说明：  什么是GUI呢 ? GUI是Graphical User Interface 图形用户界面的意思，象很多高级 编程语言一样，Matlab也有图形用户界面开发环境，随着计算机技术的飞速发展， 人与计算机的通信方式也发生的很大的变化，从原来的命令行通讯方式（例如很早 的DOS系统）变化到了现在的图形界面下的交互方式，而现在绝大多数的应用程序 都是在图形化用户界面下运行的
(What is a GUI then? GUI is a Graphical User Interface graphical user interface means, like a lot of the same high-level programming language, Matlab also has a graphical user interface development environment, with the rapid development of computer technology, human and computer communications have taken place in a large changes, from the original command-line means of communication (such as an early DOS systems) change to the current interactive graphical interface mode, and now the vast majority of applications are in a graphical user interface running under)
