WebIn Matlab this would be possible with the corr function corr(X,y). For Python however this does not seem possible with the np.corrcoef function: import numpy as np X = np.random.random([1000, 10]) y = np.random.random(10) np.corrcoef(X,y).shape Which results in shape (1001, 1001). But this will fail when the dimension of X is large. Web该函数的语法如下： numpy.corrcoef (x, y=None, rowvar=True, bias=, ddof=, fweights=None, aweights=None) 参数说明： - x：要计算相关系数矩阵的数据，可以是一个数组或一个矩阵。 - y：如果y不为None，则计算x和y之间的相关系数矩阵。 如果y为None，则计算x内部的相关系数矩阵。 - rowvar：如果rowvar为True（默认值），则每 …
