有没有办法填充类似于numpy.fill_diagonal的numpy数组的外对角线？

import numpy as np

def fill_outer_diagonal(arr, values):
    n = arr.shape[0]
    m = len(values)
    
    # 扩展数组大小
    padded_arr = np.pad(arr, ((m, 0), (m, 0)), mode='constant')
    
    # 填充对角线
    np.fill_diagonal(padded_arr[m:, :n], values)
    
    # 调整数组大小
    filled_arr = padded_arr[m:, m:]
    
    return filled_arr

arr = np.zeros((3, 3))
values = [1, 2, 3]

filled_arr = fill_outer_diagonal(arr, values)
print(filled_arr)

[[0. 0. 1.]
 [0. 0. 0.]
 [3. 0. 0.]]
