关于返回矩阵算法Python的问题

import numpy as np

def matrix_addition(matrix1, matrix2):
    result = np.add(matrix1, matrix2)
    return result

def matrix_multiplication(matrix1, matrix2):
    result = np.dot(matrix1, matrix2)
    return result

# 示例矩阵
matrix1 = np.array([[1, 2], [3, 4]])
matrix2 = np.array([[5, 6], [7, 8]])

# 矩阵加法
addition_result = matrix_addition(matrix1, matrix2)
print("矩阵加法结果：")
print(addition_result)

# 矩阵乘法
multiplication_result = matrix_multiplication(matrix1, matrix2)
print("矩阵乘法结果：")
print(multiplication_result)
