主元分析法的C语言程序，主要用在降维的方面，也可用在信号处理，故障诊断。-Principal Component Analysis Method C language program, mainly used in dimensionality reduction, can also be used in signal processing, fault diagnosis.

用于图像或者信号高维特征的降维程序，包含KLPP,OLPP和PCA等程度-for dimensionality reduction

用于特征降维，特征融合，相关分析等,真的是一个好程序，相参脉冲串复调制信号。- For feature reduction, feature fusion, correlation analysis, Really is a good program, Complex modulation coherent pulse train signal.
