用MATLAB实现加噪信号的消噪,用了三种常用方法。(de-noise programme by MATLAB，it is very useful for newerws.)

仿真MATLAB，史密斯，模糊，神经网络都有 SIMULINK搭建(Simulation MATLAB, Smith, fuzzy, neural network structures have SIMULINK)

cvlib_mex为已封装了openCV重要函数的库，PS：此文件供linux系统下64位matlab使用(cvlib_mex as an important function encapsulates the openCV library, PS: This file is for 64-bit linux system using matlab)

说明：  传染病模型是指传染病的基本数学模型，研究传染病的传播速度、空间范围、传播途径、动力学机理等问题，以指导对传染病的有效的预防和控制。常见的传染病模型按照传染病类型分为SI、SIR、SIRS、SEIR模型等。由于2019年末出现的新冠肺炎有一定的潜伏期，与病人接触过的健康人并不马上患病，而是称为病原体的携带者，归为E类。(infectious disease model simulation)

无线传感器网络节点定位算法研究，APIT定位算法的源代码(Wireless sensor network node localization algorithms, APIT localization algorithm source code)

很好的粒子图像测速（PIV）Matlab源代码，本人在Matlab 2010下测试通过。(Particle image velocimetry (PIV) Matlab source code, I tested it using the Matlab 2010.)

MCMC绝对可以运行，在matlab7.1上测试过的，OK(The MCMC absolutely can run)

说明：  对一个矩阵进行Cholesky分解的matlab程序(the cholesky decomposition of one matrix)

寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)
