在Matlab中，用PCA程序提取两个统计量：T2和Q从而应用在机械故障的预测中，我个人觉得还可以，希望大家指正。(In Matlab, with the PCA program to extract the two statistics: T2 and Q and thus used in the prediction of mechanical failure, I personally felt that I can and hope that we corrected.)

自适应滤波的matlab代码，非常实用，可配合专门的书籍参考(Adaptive filtering matlab code, very practical, with special reference books)

说明：  这个模型可以在MATLAB中，为数据库的进入，提供时间倒数，以防止过多地试密码，从而提高系统的保密性( TIMEOUT = LOGINTIMEOUT(FIRSTARG,SECONDARG) returns the current value of time allowed for a connection to a database to be successful. FIRSTARG, an optional argument, is a string that specifies the JDBC driver to be used establishing the database connection. SECONDARG, an optional argument, is an integer that specifies the length of time the driver will attempt to make a connection to a database. If FIRSTARG is not specified then the default JDBC/ODBC bridge is used to establish the connection to the database. If function is used without arguments then the current time out value is returned. )

这是对广义高斯分布中两个参数alpha,beta的估计方法，对自然图像的大量统计特征就符合这一分布。(function [f, g] = dggbeta(beta, absx) DGGBETA Derivative of generalized Gaussian pdf with respective to beta [F, G] = DGGBETA(BETA, ABSX) Return partial derivative and second order partial derivative This is an utility function for GGMLE ABSX is the distance of the data from the mean Function is undefined for negative beta if beta <= 0 f = NaN g = NaN )
