数据资料是数学模型与实际问题接轨的重要途径和手段，有时还可以直接从数据资料中发现规 律组建模型。数据分析和处理是统计学研究的主要内容，也是计算数学的工作领域，近年来随 着计算机科学的发展，对“海量”数据的分析形成了一门新的交叉学科“数据挖掘”。这一章仅 介绍用统计学的最小二乘法构造拟合数据模型，以及用计算数学的函数插值方法处理数据解决 实际问题。(Is a mathematical model of data integration an important practical problem with the ways and means, and sometimes directly from the data can also be found in the law of the formation model. Statistical data analysis and processing is the main research, but also work areas of computational mathematics, computer science in recent years, along with the development of the " mass" analysis of the data formed a new cross-disciplinary " data mining." This chapter describes only the structure with a statistical method of least squares fit data models, and computational mathematics and data processing function interpolation methods to solve practical problems.)

Programming Matlab and C++,混合编程；经典教程；

说明：  在DOS下一个VGAL库的源程序。用TC3进行编译成功。(DOS VGAL a library of the source. Compiled with TC3 success.)

图像的matlab处理，包含图像的压缩，zigzag算法应用，图像加密，图像解密等(Matlab image processing, compression containing images, zigzag algorithm, image encryption, decryption image)

这本Matlab编程是Stephen J. Chapman的经典作品，本上独特的强调自上而下的编程方法，而且在全书中皆有提醒和注意常犯的错误(This is Stephen J. Chapman Matlab programming classics, this emphasis on the unique top-down programming, but also in the book have the sound alerts and attention to common mistakes)

说明：  a text searching algorithm, still not completed but I will finish it soon.
