用于信号特征提取、信号消噪，多元数据分析的主分量分析投影，粒子图像分割及匹配均为自行编制的子例程，采用的是脉冲对消法，相关分析过程的matlab方法，用于特征降维，特征融合，相关分析等。- For feature extraction, signal de-noising, Principal component analysis of multivariate data analysis projection, Particle image segmentation and matching subroutines themselves are prepared, It uses a pulse of consumer law, Correlation analysis process matlab method, For feature reduction, feature fusion, correlation analysis.
