求时间序列的最大李亚普诺夫指数，很好用。(the largest lyapunov)

This is an matlab source code for smoothed particle hydrodynamic simulaiton. It include matlab routines and input data.

说明：  基于非负矩阵分解（NMF）的人脸特征提取算法，NMF基本思想是找到一个线性子空间W，使的构成子空间的基本图像的像素点都是正值，而且人脸图像在子空间上的投影系数也是正数(Non-negative Matrix Factorization (NMF) of facial feature extraction algorithm, NMF basic idea is to find a linear sub-space W, so that the composition of sub-space of the basic image pixels are positive, and face image in the sub-space projection coefficient is positive)

本程序是用于信号频谱分析的实验程序。 主要功能是进行信号的幅值谱计算；同时可完成在选定范围内谱峰的精确计算。( This procedure is used to test the program signal spectrum analysis. Main function is to calculate the signal amplitude spectrum the same can be done accurately calculate the spectral peaks within the selected range.)

实现伪随机序列 关键词 随机矩阵 本源多项式 移位运算(Achieve the pseudo-random sequence Key words random matrix origin polynomial shift operator)

ldpc编译码包括生成矩阵算法，稀疏矩阵编码，概率译码等等(ldpc encode and encode)

基于人耳遮蔽效应谱减法的语音增强算法，matlab(Enhancement based on spectral subtraction ear shadowing speech，matlab)

牛顿法的MATLAB，随便写的水平有限请谅解(Newton' s law of MATLAB, low level of random write requests with the understanding)

说明：  MATLAB开发的计算机一个。直接运行即可。(MATLAB CALCULATOR)
