功率谱密度的仿真，以matlab软件为基础，实现了多种谱密度的变换(Simulation of the power spectral density)

计算一维光子晶体的投射和反射，TM模式，PML边界条件，总场散射场模式，高斯脉冲，并已优化(One-dimensional photonic crystal projection and reflection, PML boundary conditions, the total field scattered field model, Gaussian pulse, and has been optimized)

采用matlab编程语言，主要功能用于读取grd文件。(read grd document)

HHT变换matlab程序 在matlab下运行即可，可以修改各种参数，采样点数，各种电能质量原始信号均由程序所得，可以信号叠加而来。比如电压跌落，谐波，暂时上升，中断等。 例子给出的是 电压暂降。(HHT transform matlab matlab program can be run in, you can modify various parameters, sampling points, a variety of power quality of the original signal by the program proceeds, may signal superimposed from. Such as voltage drop, harmonics, temporary rise interruption. The example given is voltage sags.)

通过重心法确定光斑图像的中心。根据个像素的灰度值和所在的位置乘积和总面值作比，进而求得重心。(Through the center of gravity method to determine the center of the image spot. According to the gray-scale pixel value and the location of the product and the total for more than face value, and then get the focus.)

前馈ANC系统的模型，但是，不详细，可以参考！(the model of two earphone active noise control)

MATLAB教程ppt 第六～九章 简练明了 (the ppt about matlab)

说明：  本人提交的用matlab的关于滤波器设计的作业，很有用的　(I used Matlab submitted on the design of filter operation, a very useful)

本程序主要针对计算机模拟进行相关程序的编写！(The program focused on the preparation of related computer simulation program!)
