本文实现了众所周知的PCA算法。它返回一个减少号尺寸/特征数据集。折减系数，即多少特征最终/减少集应该包含可由用户选择。

它包含一个面说明数据集（脸。垫）（请参阅自述文件）如何使用。-this implements the well known PCA algorithm. It returns a Dataset with reduced no. of dimensions/features. The reduction factor i.e how many features the final/reduced Dataset should contain can be chosen by the user.



It contains a illustration dataset of faces (face.mat)(please see Read-me file) to show the usage.
