说明：  作为一个功能强大的工具软件，Matlab具有很强的图形处理功能，提供了大量的二维、三维图形函数。由于系统采用面向对象的技术和丰富的矩阵运算，所以在图形处理方面即常方便又高效。
(As a powerful software tool, Matlab has a strong graphics capabilities, providing a large number of two-dimensional, three-dimensional graphics functions. Since the system uses object-oriented technology and rich matrix computation, graphics processing, so that is often convenient and efficient.)
