PCA based face recognition

This tutorial is designed to give the reader an understanding of Principal Components Analysis (PCA). PCA is a useful statistical technique that has found application in fields such as face recognition and image compression, and is a common technique for finding patterns in data of high dimension. Before getting to a description of PCA, this tutorial first introduces mathematical concepts that will be used in PCA. It covers standard deviation, covariance, eigenvectors and eigenvalues. This background knowledge is meant to make the PCA section very straightforward, but can be skipped if the concepts are already familiar.

层次分析法（Analytic Hierarchy Process简称AHP）是将与决策总是有关的元素分解成目标、准则、方案等层次，在此基础之上进行定性和定量分析的决策方法。这里提出层次分析法的matlab源程序(AHP (Analytic Hierarchy Process referred AHP) is always associated with the decision-making elements into goals, guidelines, programs and other levels, on this basis for qualitative and quantitative analysis of decision-making methods. AHP presented here matlab source)

这是一个永磁同步电机的驱动系统仿真模型，使用空间矢量控制方法，控制效果不错(this is a simulating model of pmsm svpwm under simulink)

matlab实现deeplearning的教程，很详细(matlab realize deeplearning tutorial, a very detailed)

【Matlab界面GUI添加背景图片】：好像桌面背景一样，添加自己想要的背景图片，这里面有个技术，可以让背景不影响GUI界面的文字，edit、text。具体代码下载了解一下吧，平时工作总结的方法。(Matlab interface [GUI] Add a background image: It seems as desktop background, you want to add your own background image, and there are a technology that allows the background without affecting the GUI interface text, edit, text. Specific code to download understand it, the usual method of summing up the work.)

该程序用Dijkstra算法寻找最小路径。输入为起点，终点，邻接矩阵。输出为最短距离，最短距离对应的路程。代码有详细注释说明。(The procedure used Dijkstra algorithm to find the minimum path. Enter as a starting point, end point adjacency matrix. The output is the shortest distance, shortest distance corresponds to the distance. Codes are detailed explanatory notes.)
