利用平面波计算了正方格子椭圆柱光子晶体的能带结构(use of a plane wave calculation square elliptical cylinder photonic crystal structure of the band)

matlab代码，判定点是否在简单封闭曲线（允许非凸）内部。曲线必须以点集形式给出。(matlab code, to determine the relation between a point and a simple closed curve(allow non-convex). Curve must be given in the form set of points.)

The Finite Element Method Using MATLAB

基于BP神经网络对传感器非线性系统进行建模，用的是BP神往网络的工具箱在MATLAB 软件进行仿真！(Based on the BP neural network model of sensor nonlinear systems, with BP charmed network software MATLAB toolbox in simulation! )

说明：  基于基本牛顿法求极值点需注意： 初值点要接近极值点，否则不收敛 (Newton s Method function extremum)

求电力系统状态估计ieee9节点 的雅阁比矩阵(Seeking power system state estimation Accord than ieee9 node matrix)
