C语言编写的PCA程序，实现主成分分析功能-C language of the PCA program to achieve the principal component analysis function

该程序包实现了模式识别中的两个特征提取算法，主成分分析PCA和线性判别分析LDA。采用C++语言编写，开发环境VS。 程序包还提供了两个测试样本文件。-The package to achieve the recognition of the two feature extraction algorithm, principal component analysis PCA and linear discriminant analysis LDA. Using C++ language, dev

PCA降维，将特征以二维矩阵形式输入，对特征进行降维处理。(PCA dimension reduction, the characteristics of a two-dimensional matrix input, the feature dimensionality reduction.)
