powell

calculates the bentley sweep algorithm between two trapezoidal membership functions

给出一个逆变器具体的仿真实例，通过仿真 ，可以得出实际运行中的电压、电流的波形 (Give a concrete example of the simulation, the simulation can be drawn from the actual operation of the voltage and current waveforms)

最速下降法又称为梯度法，是1847 年由著名数学家Cauchy 给出的，它是解析法中最古老的一种，其他解析方法或是它的变形，或是受它的启发而得到的，因此它是最优化方法的基础。这里给出其Matlab源程序。(The steepest descent method, also known as gradient method, was in 1847 given by the famous mathematician Cauchy, it is the oldest analytical method one, other analytical method or its variants, or inspired by it obtained and therefore it is the basis for the optimization method. Here are its Matlab source.)

Simple MultiLevel Inverter Design

在matlab或者PSCAD中对桥差不平衡电流进行仿真计算，得到仿真结果与常规计算结果一致，此方法修改简单快捷。(In matlab or PSCAD to bridge the difference between the current imbalance in the simulation calculation, the simulation results are consistent with conventional calculations, this method is simple and quick modification.)

最大流最小截问题，用ｍａｔｌａｂ编写的，ｒａｒ中有说明，较清晰(Maximum flow minimum cut problem, written with matlab, rar have stated more clearly)

matlab m语言的编程，包括m语言的编程基础，C语言转换和外部接口等(matlab m language programming, including m basics of programming language, C language conversion and external interfaces)

一直用途比较大的调制方式，高斯最小移频键控，在simulink中有比较大的参考价值(Has been the use of relatively large modulation, Gaussian Minimum Shift Keying reference value in simulink)
