The most familiar measure of dependence between two quantities is the Pearson product-moment correlation coefficient (PPMCC), or "Pearson's correlation coefficient", commonly called simply "the correlation coefficient".

corr 这种是随机变量联合采样样本的相关性,虽然也表示成了向量的形式,但它与向量正交不是一回事

你这是两串数的关联性,看程序应该是 Pearson 相关系数,样本是 1 维样本,和向量有啥关系?
