说明：  用QR分解来解方程AX=b，其中QR分解是用householder变换做的(With QR decomposition to solve the equation AX = b, where QR decomposition is done using householder transformation)

随着应用的越来越复杂，对数据同步和存储的要求越来越多，有时候我们面对大量复杂的数据加载和数据同步代价，尤其是如果单服务器无法承载大量应用数据的时候，我们如何可以实现动态扩展服务器已达到负载均衡的目标(As applications are becoming more complex, the data synchronization and storage requirements are more and more, sometimes we are facing a large amount of data loading and data synchronization costs, especially if a single server cannot load a lot of the time of application data, how can we realize the dynamic extension of the server has reached the aim of load balancing)

关于多智能体遗传算法优化神经网络的MATLAB程序(On multi-agent genetic algorithm to optimize the MATLAB neural network program)

repval(X) finds all repeated values for input X, and their attributes. (The input may be vector, matrix, char string, or cell of strings Y=repval(X) returns the repeated values of X [RV, NR, POS, IR]=repval(X) returns the following outputs RV : Repeated Values (sorted) NR : Number of times each RV was repeated POS : Position vector of X of RV entries IR : Index of repetition Example: X=[1 5 5 9 5 5 1] [RV,NR,POS,IR]=repval(X) Output: RV = [1 5] Numbers 1 and 5 are repeated values NR = [2 4] Respectively repeated 2 and 4 times POS = [1 7 2 3 5 6] Position index of X for repeated values IR = [1 1 2 2 2 2] Corresponding to which index of RV )
