在matlab中编程实现的正交多项式最小二乘拟合函数,调用格式：a=zjzxec(x,y,m)(In the matlab programming in the orthogonal polynomial least squares fitting function, call format: a = zjzxec (x, y, m))

一个描述左手材料的一维FDTD程序，适合初学者参考。(A description of the one-dimensional FDTD program of the left-handed materials and reference for beginners.)

机加工自由曲面，由matlab生成设计曲面和设计刀具轨迹（此例为加工椭球面）(Freeform surface machining, surface generated by the matlab design and design tool path (in this case for the processing of the ellipsoid))

双层优化模型，求解思路是：首先对上层的决策变量编码，代人下层规划模型，通过求解下层模型的决策变量值，代入上层模型计算适应度值，然后进行交叉、变异、选择操作，最后求出最优解(two-layer optimization)

APF仿真，才用滞环控制，输出系统所需波形，补偿波形提取使用瞬时无功算法(Active Power Filter simulation)
