Image-Processing

two methods of calculating eucledian distance are shown in the m files

非常不错的QPSK在matlab中的仿真教程，文档中包含相关的所有代码(very good QPSK in the Matlab simulation Guide, the document contains all the related code!)

蛙跳积分法数值模拟Duffing方程和单摆运动的matlab程序(Numerical simulation leapfrog integration Duffing equation and pendulum motion)

改程序为叶片振动在线检测的速矢端迹法程序，有研究叶片振动在线检测的朋友可以参考(Change the procedure for the blade vibration online testing of hodograph method procedures, research blade vibration online testing can refer a friend)

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.)

This demo shows how to use MATLAB, Optimization Toolbox, and Genetic Algorithm and Direct Search Toolbox to optimize the design of a double wishbone suspension system.

Matlab图形背景代码 包括导入数据、进度条、当前时间、主界面窗口设置等等。(Matlab codes of graphic background)

DTFT的实现 适用于初学者的适用于初学者的适用于初学者的(Implementation of DTFT)

image retrieval,content based image retrieval

关于介绍小波在信号和图像中的应用，有大量例子说明~(On the introduction of wavelet in signal and image applications, there are numerous examples to illustrate ~)
