matlab的基础知识ppt03，适合初学者，希望大家好好学习(matlab basics ppt03, suitable for beginners, I hope you learn)

kalman 滤波的 matlab 程序(kalman filter matlab program)

this is a curvelet transform

说明：  电力系统拓扑分析、孤岛数，关联矩阵法把主接线的节点和母线的每一进出线连接点作为拓扑图的节 点，把开关元件作为拓扑图的支路，建立节点．支路关联矩阵表示电网的基本拓 扑结构。然后定义矩阵“与．或’’乘法运算，利用连通性的传递性质实现对电力 网络结构的辨识。(In the incidence matrix method, the node of the main connection and the connection point of each incoming and outgoing line of the bus are taken as the node of the topology diagram, and the switching element is taken as the branch of the topology diagram to establish the node.The branch correlation matrix represents the basic topology structure of the power grid)
