【code】

import numpy as np# 创建随机交换的索引permutation = list(np.random.permutation(3))# 创建矩阵X,YX = np.array([[0, 1, 2], [0, 1, 2], [0, 1, 2]])Y = np.array([[0, 1, 2]])# 交换顺序shuffled_X = X[:, permutation]shuffled_Y = Y[:, permutation]# 输出print("permutation:")print(permutation)print("X:")print(X)print("Y:")print(Y)print("shuffled_X:")print(shuffled_X)print("shuffled_Y:")print(shuffled_Y)

【result】
