如何将数组的值添加到矩阵的列中？

import numpy as np

# 原始矩阵
matrix = np.array([[1, 2, 3],
                   [4, 5, 6],
                   [7, 8, 9]])

# 要添加的数组
array = np.array([10, 11, 12])

# 创建新矩阵
new_matrix = np.zeros((matrix.shape[0], matrix.shape[1]+1))

# 复制原始矩阵到新矩阵
new_matrix[:, :-1] = matrix

# 将数组的值添加到新矩阵的最后一列
new_matrix[:, -1] = array

print(new_matrix)

[[ 1.  2.  3. 10.]
 [ 4.  5.  6. 11.]
 [ 7.  8.  9. 12.]]
