本程序是EM算法，是参数估计（极大似然估计）方法的数值解法。(This procedure is the EM algorithm, is the parameter estimation (MLE) method of numerical solution.)

压缩感知经典方法，也是单像素相机刚开始使用的方法。(Compressed sensing classical methods, but also the beginning of single-pixel camera, the method used.)

这是一个三相交流的下垂控制仿真，使用传统的下垂控制策略(This is droop control model of three phase grid using the traditional droop control method)

power_sfavg.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_sfavg.rar, ,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

对K-means聚类算法的改进X-means算法。针对K值如何设定的问题，利用BIC准则判断聚类点数量。同时附有两个初始聚类点的选择程序，自己选吧。(The improved X-means algorithm for K-means clustering algorithm. In view of the problem of how to set the K value, the number of clustering points is judged by the BIC criterion. At the same time, there are two initial clustering points of the selection program, choose it yourself.)

Black and white Image contrast enhancement.
