粒子群进化算法，标准的源代码程序和实例教程。(Evolutionary particle swarm algorithm, standard procedures and examples of source code tutorial.)

K-means is a clustering algorithm In the beginning we determine number of cluster K and we assume the centroid or center of these clusters. We can take any random objects as the initial centroids or the first K objects in sequence can also serve as the initial centroids. There are two function for that the kMeanCluster and distMatrix

g(x)=f(m,n,L), 其中,m,n,L均服从正态分布,分布情况也在所给的图中. 使用matlab,用蒙特卡罗模拟法 对该函数进行模拟,得出g(x)大于0的概率.(G (x) =f (m, N, L), of which, m, N, L are the normal distribution, distribution is also in the picture. The use of MATLAB, simulates the function by Monte Carlo method, the G (x) greater than 0 probability.)

循环冗余校验就是一种被广泛采用的错误检验编码。介绍了循环冗余校验码的差错控制原理及其算法实现。(CRC is a widely used test coding errors. Introduced a cyclic redundancy check code for error control principle and algorithm.)

错误隐藏matlab 代码，很不错的pocs(error concealment)
