Matching Pursuit方法，经典的稀疏表示方法，可以用人脸识别和图像分类，图像去噪，现在非常流行。(Matching Pursuit method, sparse representation of the classic, you can use face recognition and image classification, image denoising, now very popular.)

用wolf方法计算时间序列的最大lyapunov指数(Calculated by wolf maximum lyapunov index time series)

基于simulink设计的飞行器飞行轨迹恢复程序，非常好，我调试过，matlab2010b下运行(Simulink design-based aircraft flight path recovery program is very good, I debugged, matlab2010b running)

STFT parameter for ECG data

用于检测微弱信号的Duffing系统，这是我的毕业设计一部分，因为我做的时候也曾求取过很多资料，但是并没有找到，因此在我完成之后，上传这个代码，希望这个能帮助别人。 里面还有后续做的GUI界面实现的Duffing振子检测功能，可检测信号幅值和频率。(The Duffing system for detecting weak signals, this is part of my graduation project, because I also asked for a lot of information when I did it, but it was not found, so after I finished, upload this code, I hope this can help others.)

说明：  matlab 实现的全景图像拼接，希望对大家能有所帮助(matlab implementation of the panoramic image mosaic, we want to help)

视频读取及目标背景提取，matlab平台下可以对视频取帧(Read and goals video background extraction, matlab platform can take video frame)

对matlab做了简介。通过一个魔方矩阵介绍了matlab矩阵的编程与算法；介绍了m文件的创建及简单作图。适合入门。(Introduction of matlab. Matrix introduced through a cube of programming and algorithm matlab matrix introduced m file creation and simple graphics. For entry.)

实现图像的直方图,该函数功能强大，已经通过matlab运行(it can realize a image s hist! )

This package enables Gaussian process prediction with very large sample sizes with a much smaller computational burden than many existing methods.
