可以直接画出lorenz系统在各种参数下的3D演化吸引子和分叉图(Can directly draw the evolution of the the lorenz system in the various parameters of the 3D attractor bifurcation diagram)

雷达仿真程序，包括雷达系统中会用到的一些常用程序(Radar simulation program, including the radar system will be used in some commonly used procedures)

RGB to gray scale conversion of image.

基于matlab的语音回波抵消系统仿真设计中FFT转换部分程序(Voice echo cancellation system based on matlab simulation in the design of FFT transform part of the program )

抗jsteg的隐写分析，jsteg jpeg图像隐写的重要方法之一。(Anti-jsteg of steganalysis, jsteg jpeg image steganography one of the important ways.)

householder transformation

提取Harris角点程序，非常好用的角点提取程序(Harris corner extraction program, very easy to use corner detection process)

该程序实现多特征红线报警算法，两个matlab文件，一个为函数，另一个为主函数，调用该函数文件；该程序将4路信号，每一路信号的特征量值及其固定阈值求出来，并一起画出图来。(The program features multi-red alarm algorithm, two matlab files, one for function, the other main function calls the function file the program seek out four signals characteristics of each road and fixed threshold value ,then draw them out .)

利用R的toepliz性质，是实数，则r也应该是实数，是实信号r(-m)=r(m)(Toepliz the nature of the use of R is real number, then r should be real, real signal r (-m) = r (m))
