中文说明：基于核的主成分分析算法（kpca），用matlab编的，在原有的线性主成分分析的基础上，加上核分析，比线性的分析结果更加准确。
English Description：
Based on kernel principal component analysis algorithm (kpca), series with MATLAB, on the basis of the original linear principal components analysis, plus nuclear analysis and analysis results are more accurate than the linear.
