这篇文章是盲信号处理，因为是英文文章，所以大家看内容就好了。(Principal component analysis (PCA) is a mainstay of modern data analysis- a black box that is widely used but poorly understood. The goal of this paper is to dispel the magic behind this black box. This tutorial focuses on building a solid intuition for how and why principal component analysis works furthermore, it crystallizes this knowledge by deriving from simple intuitions, the mathematics behind PCA . This tutorial does not shy away from explaining the ideas informally, nor does it shy away from the mathematics. The hope is that by addressing both aspects, readers of all levels will be able to gain a better understanding of PCA as well as the when, the how and the why of applying this technique.)

kinect深度相机采集数据，平面点云数据，通过拟合点云平面，分析点云精度。

这是一个永磁同步电机直接转矩控制的例程，包含mdl文件以及m文件，可直接运行(This is a permanent magnet synchronous motor direct torque control routines, including MDL files and M files, can be directly run.)

1、初始化： 1.1每一个空间的点映射到二维窗格，每个空间的点分配唯一的二维窗格坐标。一个窗格只能有一个点。 1.2为每一只蚂蚁在二维窗格分配唯一的地址 （第一步需要注意的是：空间上点的位置和平面窗格上点的位置完全是两回事，空间上两个点的位置来计算两点之间的距离；而平面上点的位置，主要是用来确定半径为S的区域内的点，计算两个点的空间距离，进而计算群体相似度，最后通过群体相似度来计算拾起或者放下的概率） 2、迭代日最高气温次 3、所有的蚂蚁运动一次 4、产生一个0-1之间的随机数R
