说明：  四阶龙格—库塔算法。自己在课程设计中就是用的这个算法。对于初学者有一定的帮助(Fourth order Runge- Kutta method. Own course design is to use this algorithm. Be helpful for beginners)

使用MATLAB语言实现BP神经网络的分类功能，代码很简洁(using MATLAB BP neural network classification function, a very simple code)

说明：  实现数字水印的嵌入，提取，以及受攻击后的提取(The realization of digital watermark embedding, extraction, and the extraction after attack)

这个是一个自己做的程序，可以进行相关的操作，初学者(This is a program to do their own, can be related to the operation, for beginners)

The principal characteristic of VSC-HVDC transmission is its ability to independently control the reactive and real power flow at each of the AC systems to which it is connected, at the Point of Common Coupling (PCC). In contrast to line-commutated HVDC transmission, the polarity of the DC link voltage remains the same with the DC current being reversed to change the direction of power flow.

基于Matlab的低通滤波器的设计源码，可以通过此代码，模拟低通滤波器的设计。并附有仿真后的图像。(Matlab low pass filter based on the design of source code, can this code, analog low-pass filter design. Together with simulation, the image.)
