This can be used to describe convolution in time domain is equivalent to multiplication in frequency domain.This also consist of generating the cazac sequences.

粒子群优化算法（PSO）是一种基于种群的随机优化技术，由Eberhart和Kennedy于1995年提出。粒子群算法模仿昆虫、兽群、鸟群和鱼群等的群集行为，这些群体按照一种合作的方式寻找食物，群体中的每个成员通过学习它自身的经验和其他成员的经验来不断改变其搜索模式。 (Particle swarm optimization algorithm (PSO) is a population based stochastic optimization technique, put forward by Eberhart and Kennedy in 1995. Particle swarm optimization (pso) algorithm on insects, herds, flocks and schools of fish swarm behavior, and these groups to find food in a cooperative way, each member of the group itself by learning experience and the experience of the other members to continuously change its search pattern.)

FRFT算法实现程序，用分数阶傅里叶变换进行信号处理，得到对应的视频图(frft simulation using matlab)

主成分分析代码，用matlab实现的，请大家参阅。(Principal component analysis code, matlab implementation, please refer to the.)

说明：  皮肤检测程序，弄一张皮肤组合图定义为sample.jpg就可以使用(Skin testing procedures, get a skin graph is defined as the combination can be used sample.jpg)

说明：  matlab 图像处理 显示两幅子图像的归一化互相关(matlab image processing show that two sub-image of normalized cross-correlation)

不同刚度对临界转速值得影响，也是matlab程序。有分析内容。(Different stiffness of the critical speed is worth, is also a matlab program. Tired ah)
