用matlab实现霍夫曼编码与解码，可以直接运行。(Matlab Hoffman used to achieve encoding and decoding, can be directly run.)

MIT-BIH心电数据库中包含有大量的心电信号，用户可以直接下载这些信号用于信号分析，算法验证等。但是其数据存储格式复杂，只能用其提供的工具包进行读取，很不方便。本源码可以直接读取MIT-BIH中的format212和format16格式的心电数据，免去了学习其繁琐工具包的过程。(MIT-BIH ECG database contains a large number of ECG signals, users can directly download these signals used in signal analysis, verification algorithm. However, the complexity of its data storage format, can only provide a toolkit to read, very inconvenient. The source can be directly read the MIT-BIH in format212 and format16 ECG data format, which eliminates the cumbersome tool kit to learn their process.)

bayes分类器 Bayes classifier for Gaussian distributiuon 直接可以解压缩(Bayes classifier Bayesian classifier for Gaussian di stributiuon can directly extract)

宽带模糊度函数程序，程序中包含了PCW、LFM、HFM和HFM+PCW四种信号，可以自行选择。(The ambiguity function program)

说明：  人脸识别代码：图像工程中经常用到的一个实用算法。这里是matlab的实现。(Face recognition code: Image Engineering frequently used for a practical algorithm. Here is the realization of matlab.)

说明：  这些文章讲述了分步傅里叶方法，通过这些方法可以数值解非线性薛定谔方程，并且模拟光在光纤中传输随距离变化的状态，是学习光传输比较好的资料(The article was about a split-step Fourier method, numerical solution of these methods can be non-linear Schrodinger equation, and simulation of optical fiber transmission in the state of change with distance, is to learn good information on optical transmission)

说明：  采用一种离散微分跟踪器的PID控制。被控对象是三阶传递函数，参考输入rin=20，干扰信号是0.5rands（1）。(PID Controller with Partial differential)

一维抛物方程差分格式，数值分析作业，（向后的方法）(One-dimensional difference scheme for parabolic equations)

说明：  本程序实现多模态故障检测与故障诊断，用的方法是pca_GMM_FJ，对象为TE,GMM是用的FJ算法，效果很好(This procedure realize multimodal, fault detection and fault diagnosis method is pca_GMM_FJ, object for TE, GMM FJ algorithm is used, the effect is very good)

关于高阶循环累积量的的程序，用于信号调制识别(high order cyclic cumum)
