首先介绍MATLAB的基本知识及基本运算，使读者对MATLAB有一个概略的了解，然后系统论述图形绘制技术的基本概念、工作原理及在工程中的应用。书中精选科学和工程中常用的多个算法，全部采用MATLAB语言编程实现，并结合实例对算法程序进行验证和分析。其中详细讲解了MATLAB的基本知识、二维图形的绘制、三维图形的绘制、高级图形绘制技术、动画与视频、几何造型及GUI的程序设计等内容。(First introduced in MATLAB basic knowledge and basic operations, allowing the reader to have a rough understanding of MATLAB and then systematically discusses the basic concepts of graphics rendering technology, working principle and in engineering. The book featured commonly used in science and engineering multiple algorithms, all using MATLAB programming language, with examples for algorithm verification and analysis. Which explained in detail the basics of MATLAB, two-dimensional graphics rendering, 3D graphics rendering, advanced graphics rendering, animation and video, geometric modeling and GUI programming and other content.)

图像缩放的函数，基于像素复制和删除的 ，子啊matlab中可找到(based on shrinking and zooming f,we canfind it in matlab)

现代信号处理中谱估计在matlab中的使用，主要是基于mtlab的程序，实现了图像的灰度化并进一步用于视频监视控。( Modern signal processing used in the spectral estimation in matlab, Mainly based on the mtlab procedures, Achieve a grayscale image and further control for video surveillance.)

说明：  用牛顿下山法求解方程：下山因子在计算过程中可以变动，一般选择下山因子时从1开始，逐次将减半进行试算，直到能使下降条件成立为止。若当计算到某步时取不到满足要求的值（或值小到无法容忍），这时称“下山失败”，需要另取初值重新算起。(Descent method with Newton' s equation: down factor in the calculation process can change, usually selected from the 1 start down factor, will be halved for successive spreadsheet until the can down the conditions established. If when calculating the time to take a step not meet the requirements of the value (or values ??too small to tolerate), then the &quot down failed&quot , you need an alternative initial re-counting.)

说明：  利用层次分析法来解决数学或经济学中的问题，里面有AHP程序以及相应的AHP建模的讲解说明(Use of AHP to solve the problems in mathematics or economics, there are procedures and the corresponding AHP AHP modeling to explain instructions)
