如何用列向量中的值填充已知索引的矩阵中的特定元素

import numpy as np

def fill_matrix_with_vector(matrix, vector, indices):
    for index in indices:
        row_index, col_index = index
        matrix[row_index, col_index] = vector[col_index]

# 示例数据
matrix = np.zeros((3, 3))  # 创建一个3x3的全零矩阵
vector = np.array([1, 2, 3])  # 列向量
indices = [(0, 1), (1, 0), (2, 2)]  # 需要填充的特定元素索引

fill_matrix_with_vector(matrix, vector, indices)

print(matrix)

[[0. 1. 0.]
 [2. 0. 0.]
 [0. 0. 3.]]
