对一段振动信号emd分解后，求每个分量的峭度值，选取峭度最大的分量，求其包络谱，能够明显看出特征频率。(After a period of vibration signal emd decomposition, seeking kurtosis value of each component, the largest component of kurtosis, seeking its envelope spectrum, can obviously see that the characteristic frequency.)

This function computes autocorrelation with a biased scaling.

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单(This program is the most basic particle swarm optimization algorithm, using Matlab to achieve, is very simple)

说明：  用于数据建模时的样本集自动划分方法，基于X、Y矩阵的校正集及验证的划分(Automatic sample set partition method for data modeling, calibration set and validation partition based on X and Y matrices)

扩展EKF 序列最大估计，经典原码，有注释(Sequence of the largest expansion of EKF estimates, the classic original code, annotated)

电力系统分析中Ybus矩阵的去奇异变换法实现算法。该程序可以实现考虑线路分支和无线路分支的情况。(In general the power system has mutual branches and it becomes difficult to form the y bus using the inspection method, so one is to go for singular transformation method.)

说明：  重压缩检测：检测图像是否存在两次JPEG压缩并定位篡改区域(double JPEG detection)
