说明：  差分方法是求解微分方程的常用方法。本程序给出了40中差分格式的源程序。(Difference method is commonly used methods for solving differential equations. This procedure gives the difference scheme of the source 40.)

说明：  最基本的matlab函数，最全面，最基础，希望能有用(Matlab basic functions, the most comprehensive, the most basic and hope to be useful)

我自己编的一个,大家可以看看,我们可以讨论一下(my own addendum to the one, we can see that we can talk about)

希尔伯特-黄变换源代码，每一步都很详细，对初学者有很大帮助(Hilbert- Huang Transform source code, each step is very detailed and very helpful for beginners)

说明：  二阶巴特沃斯(Butterworth)低通滤波器(Low pass filter)

说明：  this file contains the medical image processing. Here, I have to find the preprocessing methods. In this implementation i have to add the salt and pepper noise.

matlab编写的视频关键帧提取程序，可自动从视频中提取帧，提取第几帧可在程序中自行设定，另附有批量处理视频的主函数。(matlab prepared video key frame extraction procedures can be automatically extracted from video frames to extract the first few frames can be set in the program, batch processing video attached with the main function.)

自己编的。采用GPS仿真信号，基于子空间正交投影的抗干扰DOA估计算法，(Using GPS signal simulation, based on subspace orthogonal projection interference DOA estimation algorithm,)
