Digital processing filtering

说明：  采用FDTD方法计算了2维光子晶体TM模的传播情况，能较直观的观察波形变化。(FDTD method using a 2-dimensional photonic crystal propagation of TM modes, can be more intuitive observation of the waveform changes.)

PSO基本算法 实现30维的球形函数的优化求值(fundermental algorithm of PSO)

This code is only intended to explain the basics behind the bandelet transform, and to be able to play with the major concepts and properties of these orthogonal basis. It does not contain any coding scheme, nor a fast implementation(This code is only intended to explain the basics behind the bandelet transform, and to be able to play with the major concepts and properties of these orthogonal basis.

说明：  用matlab编写的灰色模型程序，可以实现拟合(Gray model )

electronic,electrical circut modeing using Matlab book

backstepping applied to tracking problem of a marine vehicle

这是matlab编程的一个例子，编写M文件，实现正弦摆动的一个动画。(Matlab is a programming example, the preparation of documents M to achieve a sinusoidal oscillation of animation.)

说明：  用MATLAB仿真PID控制，其中用simulink建仿真模型，用matlab语言编写PSO算法用于优化PID参数整定。(Matlab is used to simulate PID control, in which Simulink is used to build simulation model, and PSO algorithm is written in MATLAB language to optimize PID parameter setting.)

水印嵌入算法，可实现彩色水印的嵌入，很有用的(Watermark embedding algorithm, the watermark can be embedded in color, very useful)
