numpy数组按向量划分列 [英] numpy array divide column by vector

问题描述

我有一个3x3的numpy数组，我想用3x1的矢量将其每一列分开.我知道如何用向量的元素划分每一行，但是无法找到一种解决方案来划分每一列.

I have a 3x3 numpy array and I want to divide each column of this with a vector 3x1. I know how to divide each row by elements of the vector, but am unable to find a solution to divide each column.

推荐答案

您可以转置数组以在每一列上进行划分

You can transpose your array to divide on each column

(arr_3x3.T/arr_3x1).T
