中文说明：该程序首先将人脸图像读入内存，并转换为矩阵，将多维矩阵换成一维向量，即为特征向量。 通过对特征向量实现特征脸算法，实现对人脸的识别运行>>example, 从目录中选择training set 和 testing set, 结果显示为: they are matched.
English Description：
The program will first face image is read into memory, and converted to matrices, multidimensional matrices, replaced by a-dimensional vector, and is the feature vector. Based on feature vectors eigenface algorithm realization of face recognition to run >>example from a catalog of training set and a testing set, display results as: they are matched.
