说明：  LTE天线模型仿真 LTE_System_Level_1.0_r247 2010最新(LTE--channel_gain_wrappers FROM LTE_System_Level_1.0_r247)

Objectives: The main objectives of this project: 1. Enhancement using spatial domain approach. 2. Effects of filter size, noise type and level, and repeated application. 3. Performance of Image Averaging Technique.

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)

说明：  pid仿真，控制，编程及与matlab的结合应用(pid simulation, control, programming and applications with a combination matlab)

用matlab自带函数编写的随机森林进行预测分析，此程序曾应用在kaggle比赛上。(Matlab function that comes with writing random forests predictive analysis, this program has been used in the kaggle game.)

MATLAB function to initialize and call the solve_sps2d function, which implements a 2-D solution of the nonlinear wave equation using a psuedospectral / staggered A-B method, including attenuation modeled with two relaxation mechanisms. This example demonstrates harmonic generation within a plane wave given a B/A parameter of 5.2. To increase the distance of propagation, scale the sample grid (num_axpts) by a factor(s) of 2.( MATLAB function to initialize and call the solve_sps2d function, which implements a 2-D solution of the nonlinear wave equation using a psuedospectral /staggered A-B method, including attenuation modeled with two relaxation mechanisms.
