三维有限差分算法，使用matlab编程，可以进行数值模拟(3-D FDTD code with PEC boundaries)

说明：  Matlab网格划分程序可以将结构的四边形网格转换为三角形网格。 但该文件中内容重复了mesh2tri函数写了两遍，可以删除重复部分。 Demo: clear all close all clc (Matlab grid program 1. Create mesh grid 2. Plot the original rectangular mesh 3.1 forward slash division of quadrilateral)

Aerodynamic Forces and Moments

steepsest optimization method

说明：  matlab振动试验数据分析，信号获取：测量获取设备的信号（振动、转速、过程参等）。信号分析：从信号中提取反映设备运行状态和故障的特征值。故障诊断：根据信号特征信息，对故障进行诊断（专家诊断、智能自动诊断）和预测(Matlab vibration test data analysis, signal acquisition: Measurement and acquisition of equipment signals (vibration, speed, process parameters, etc.). Signal analysis: extract the characteristic value of equipment running state and fault from the signal. Fault diagnosis: fault diagnosis (expert diagnosis, intelligent automatic diagnosis) and prediction according to signal characteristic information)

MATLAB的仿真，对于仿真有特别的贡献，基于是源码，好好。(MATLAB simulation, the simulation of a particular contribution, based on a source, well.)

Transmission Line Short Circuit Faults using MATLAB and PowerWorld, and Overloading of Transmission Lines using PowerWorld

说明：  专门讲解matlab做曲线拟合的一个教程，有示例程序的讲解，希望对大家有用(Devoted to curve fitting matlab to do a tutorial, a sample program to explain, hope to be useful)

对初学者非常有用的数学分析的最优化代码，很好用。(it is very useful.)

采用五点差分格式解决椭圆问题，这里是3个详例。(Using a five-point difference scheme to solve elliptic problems, here are three detailed examples.)
