尝试从2d张量中的特定列开始，将2d张量乘以1d张量

import numpy as np

def matrix_vector_multiplication(matrix, vector):
    # 确认维度匹配
    assert matrix.shape[1] == vector.shape[0], "维度不匹配"
    
    # 使用矩阵乘法操作
    result = np.dot(matrix, vector)
    
    return result

# 示例输入
matrix = np.array([[1, 2, 3],
                   [4, 5, 6],
                   [7, 8, 9]])

vector = np.array([1, 2, 3])

# 进行矩阵乘法操作
result = matrix_vector_multiplication(matrix, vector)

print(result)
