二维有限差分代码，利用matlab写成，比较详细，有一定学习意义(2-D FDTD code with simple radiation boundary conditions)

这个文档是基于MATLAB的语音信号LPC技术分析研究,文档详细介绍了关于语间信号的LPC技术分析(This document is based on MATLAB LPC Speech Signal Analysis and Research, the document details the language between the signals on the LPC Technical Analysis)

power_transfohyst.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_transfohyst.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

四元数双曲空间的一些计算函数，主要包括求四元数的逆，相乘运算等(Some function for the quaternionic hyperbolic space, including the inverse and the product ect.)

地震波处理软件，加速度处理信号，可以直接得到频谱描述。(Seismic processing software, the acceleration signal processing, which can be described directly by spectrum.)

Data mining, machine learning

文件当中包含两个KALMAN滤波程序： 1.最原始简单的kalman滤波程序； 2.通过KALMAN滤波解决的一个派生例子（一道数字信号处理题）； 效果不错(Paper contains two KALMAN filtering procedures: 1. The most primitive simple kalman filtering procedures 2. KALMAN filter solution through an example derived (together with digital signal processing title) the effect of good)

说明：  PID的MATLAB仿真程序，各种PID的。很全，欢迎下载(hao)

基于数据的PCA程序，程序中有故障预测，故障提取，故障预测，故障幅值估计等内容。(based on the PCA program, the program has fault prediction, fault extraction, fault prediction, fault magnitude estimation content.and so on.)
