李雅普诺夫指数的验证，只要进行变换器分岔混沌的研究(vertify Lyapouve exponent)

选择输入信号的参数，以及抽样因子，以及采样参数，对信号分别进行上抽样和下抽样，方便非均匀采样的进行。(Select the input signal parameters, and sampling factors, as well as sampling parameters, respectively, on the signal sampling and down sampling, to facilitate the conduct of non-uniform sampling.)

HFSS/UTD混合法计算电大尺寸导体上的天线(HFSS/UTD hybrid method to calculate the antenna on a large conductor)

基于短时窗能量的自适应语言端点检测程序。具有一定的抗噪声能力。输入WAV文件名，输出端点检测结果，包括数据和画图显示。(Adaptive voice activitie detection program，resistant to noice .Input with the name of wave file,output with the VAD result ,including data and figure display.)

Quantisation at different levels.

在Matlab上基于Hough变换开发的快速圆检测方法，可应用到虹膜图象的检测中，完成对虹膜内、外边缘的定位。 (in Matlab Hough transform based on the rapid development of a round detection method can be applied to the detection of iris image, the completion of the iris, outside edge positioning.)

说明：  现代通信系统MATLAB源码（刘树棠）教材配套，可以和书籍配套使用，效果很不错。(Modern communications systems MATLAB source code (刘树棠) supporting materials, and books can support the use of, the effect is pretty good.)

基于LMS自适应时延估计算法，可以进行时间延迟估计。 (Delay estimation algorithm based on LMS adaptive research based on the fractional lower order time delay estimation algorithm, including: covariation-based time delay estimation, based on the fractional lower order covariance delay estimation method, as well as the minimum norm when the average P delay estimation method.)

In this directory, we can find the eleven files. The relationship between file name and the number of program written in the book is shown in as follows.
