随着计算机技术的迅速发展和越来越广泛深入地应用于国民经济和社会生活的各个方面，随着 软件系统的规模和复杂性与日俱增，软件的生产成本和软件中存在的缺陷和故障造成的各类损失也 大大增加，甚至会带来灾难性的后果。软件质量问题已成为所有使用软件和开发软件的人关注的焦 点。由于软件是人脑的高度智力化的体现和产品这一特殊性，不同于其他科技和生产领域，因此软件与生俱来就有可能存在着缺陷。(With the rapid development of computer technology and the more extensively used in the national economy and social life in all its aspects, with the growing size and complexity of software systems, software production costs and software defects and faults caused various types of losses also increased significantly, even catastrophic consequences. Software quality has become the focus of all those who use the software and software development concern. Because the software is highly intellectual expression and product of the special nature of the human brain, unlike other areas of technology and production, so the software may be born with a defect exists.)

说明：  walsh和pn码的生成程序，用C语言实现，可供MATLAB调用(code generation process, using C language, calling for MATLAB)

文章有utd对爬行波进行循迹 给出微分几何算法 可在matlab 及vc来开发(Utd article has crawling wave of differential geometry tracking algorithm is given in the matlab and vc to develop)

VC++ and Matlab混合编程的快速实现(VC++ And Matlab Mixed Programming rapid realization of)

建立Linked List，实现插入，删除，查找等功能(Linked List )

实现频谱分析。能显示信号与频谱图。主要是对正弦信号和三角波进行一维FFT变换，得到频谱图。(To achieve spectral analysis. Shows the signal with the frequency spectrum. Sinusoidal signal and triangular wave one-dimensional FFT algorithm to obtain the frequency spectrum.)

cashcode开发,用于开发接口工具，测试等(cashcode Developmentcode)

说明：  将ELCentro波的加速度时程转换成速度、位移时程(Converting the acceleration time history of ELCentro wave into velocity and displacement time history)

16QAM的调制，它把输入的二进制数据以查找表的方式进行映射，从而提高信息传输率。(16QAM modulation, it is the input of binary data to find a way to map the table to enhance information transfer rate.)

给出了通过matlab设计IIR低通滤波器的程序，并通过程序把在DSP中所用到的变量计算出来，很有价值。(Matlab given by IIR low-pass filter design procedures, and procedures used in the DSP in the calculated variables, very valuable.)
