this code is for PCA function, used to reduce the dimension

说明：  常用的DEA交叉模型，是目前广泛使用的效率评价模型之一(DEA crossover model, which is commonly used in DEA crossover model, is one of the most widely used efficiency evaluation models at present.)

采用一种快速收敛变步长LMS（Least mean square ） 自适应最小均方算法matlab源程序，其中算法所做的工作是用FIR 滤波器的预测系统，对IIR系统进行预测，如果阶数越高越能逼近被预测系统。(Using a fast convergence of variable step size LMS (Least mean square) adaptive least mean square algorithm matlab source, one of algorithm is the work done by FIR prediction filter systems, prediction of IIR systems, if the higher order the more it can be prediction system approximation.)

图像分割的matlab程序 可以实现 并且有同步的外国论文文献 非常好用(Image segmentation matlab program can achieve synchronization of foreign papers and literature is very easy to use)

说明：  基于奇异谱的齿轮箱振动信号分析，含主程序及熵值函数。(The vibration signal analysis of Gearbox Based on singular spectrum includes main program and entropy function.)

说明：  RRT基本算法仿真，基于三维环境仿真，可更改障碍区(path planning,based on RRT algorithm,obstacle avoidance,robot,)

说明：  matlab环境下图象图形处理的基本函数的介绍以及简单示例(matlab environment images deal with the basic function of graphical presentation, as well as simple examples)
