C-C法求混沌系统的延迟时间，该程序是C-C法的函数文件，已测试，可运行多种数据，运行时间快(The C-C method seeks the delay time of the chaotic system. The program is a function file of C-C method. It has been tested and can run many kinds of data.)

该程序可以求取电力系统低频振荡特征根，输入数据为三机9节点系统(The program can strike a power system low frequency oscillation characteristic roots, the input data for the three-machine 9-bus system)

　　编写一通用的预测法分析程序，要求有一定的错误处理能力，出错后能够使程序继续运行下去，直到分析过程结束。可通过不同的文法（通过数据表现）进行测试。(Write a generic prediction analysis procedure that requires a certain degree of error-handling capabilities, enabling the program to continue after an error to run it until the end of the analysis process. Can be tested by different grammar (by performance data).)

人的面部识别程序，检测正确率很高，经过对多账户照片的识别，正确率为百分之一百(Facial recognition program, the detection accuracy is high)

扩展卡尔曼的代码,非常有用的，希望多多下载(Extended Kalman code, very useful, and I hope a lot of download)

This is a very useful code to detect copy moveimage forgery. Its input is any forged image and its output is the copied or pasted part only, by cropping the same the image.
