cosine 滤波器，主要用于通信系统中对噪声的滤除(cosine filter is mainly used in communication systems to filter out noise)

This book is a short, focused introduction to MATLAB, a comprehensive software system for mathematics and technical computing. It will be useful to bothbeginning and experienced users.

基于监督学习的一种非线性数据降维方法，可以很好地将低维特征从其所在的高维流形中提取出来，用于数据分类。(A nonlinear data dimension reduction based on supervised learning method, is a good way to the lower dimensional feature extracted from its place of higher dimensional manifold, used for data classification.)

参考外国文献，通过MATLAB程序编写了以两个简单的tDJyUc映射构造一个双混沌互扰 YOzmlLR系统,提出了基于双混沌互扰系统的无线加密算法，具有防窃听的能力，调试无错误。(References to foreign literature, through MATLAB programming the tDJyUc with two simple mapping to construct a mutual interference YOzmlLR dual chaotic systems is proposed based on the wireless encryption algorithm dual chaotic mutual interference system has the ability of anti-wiretapping, debugging errors. )

在信号分析中，我们常把信号进行矢量分解，也就是将信号分解为频率相同、峰值幅度相同但相位相差90的两个分量。该程序实现将信号分解为I路和Q路。(In signal analysis , we often decompose the signal vector , that is, the signal is decomposed into the same frequency , the peak amplitude of phase 90 of the same, but the two components . The program implementation will signal into I and Q branches .)
