实用的主分量分析程序。程序中mixedsig为 n*T 阶混合数据矩阵，n为信号个数，T为采样点数, y为 m*T 阶主分量矩阵。-The practical primary component analysis program. Program mixedsig n* T Order Mixed data matrix, n is the number of signals, T is the sampling points, y is M* T stage primary component

本程序可以实现变转速工况下对测取的信号实现重采样阶次跟踪分析。-The program can achieve variable speed operating conditions to achieve the measured signal taken resampling order tracking analysis.
