说明：  一个用MATLAB 实现的锁相环路得程序(a program of phase loop link using the tool of simulink )

说明：  上传的附件为pca主成分分析算法matlab源码(From the Annex for the PCA principal component analysis algorithm matlab source)

包括MATLAB的简单函数命令功能。。。可以用来学习Matlab，都是些能实现一定功能的代码！M-file的格式。有50多个代码。(Including simple MATLAB function command function. . . Matlab, are more able to achieve a certain function code can be used to learn! M-file format. There are more than 50 code.)

已知一对外啮合传动的齿轮的几何参数，求其啮合刚度。(to get the meshing stiffness for one pair of gear.)

本文给出了m序列多项相关性的概念，还研究了生成多项式计数的问题(In this paper, the concept of multiple correlation m series, also studied the problem of generation polynomial count)

模糊控制matlab实现，对于进行二级模糊综合评判，可编制mohufun.m函数来实现(Matlab fuzzy control)

说明：  使用PPPA计算Pareto中的超体积指标(Using PPPA to calculate Supervolume index in Pareto)
