This Project distinguish between inrush currents and internal faults in the protection of power transformers with Emtp Program And Matlab Code. Simple Methot is used in Project.

这是一种改进的粒子群优化算法，通过简单的测试函数验证(This is an improved particle swarm optimization, through a simple test function verification)

说明：  经典教材，美国人普艾克编著，非常实用的数字信号处理书(Classic textbook, edited by American Pu Yike, very practical book of digital signal processing)

MMA and GCMMA two methods for nonlinear optimization(MMA and GCMMA two methods for nonlinear optimization)

SEGMENTATION CODE FOR LUNG CANCDDER

用于聚类的matlab的EM算法程序，速度还可以。共享给大家(for clustering of the EM algorithm Matlab procedures can also speed. For everyone to share)

追赶法是适用于三对角矩阵的线性方程组求解的方法，并不适用于其他类型矩阵。(Pursuit method for solving tridiagonal matrix of linear equations, does not apply to other types of matrix.)

进行一元线性回归分析，分析的模型y=a+bx+e,e服从N(0,sigma平方),以及根据所建的一元线性回归模型进行预测实例(A linear regression analysis, the analysis of the model y = a+bx+e, e obey N (0, sigma squared), and built a linear regression model to predict instance)

说明：  画二维和三维箭头矢量，matlab工具包。直接调用。 This functin is used to draw 2D、3D-arrows. The size of arrow head is decided by the minimum distance between start and stop.(Two-dimensional and three-dimensional vector drawing arrows, matlab toolkit. Direct calls. This functin is used to draw 2D, 3D-arrows. The size of arrow head is decided by the minimum distance between start and stop.)
