python 计算两个矩阵的 Hadamard 乘积

计算两个矩阵的 Hadamard 乘积。要求输入矩阵的行/列数（在这里假设我们使用的是 n × n 的矩阵）。

    #!/usr/bin/env python3
    n = int(input("Enter the value of n: "))
    print("Enter values for the Matrix A")
    a = []
    for i in range(n):
        a.append([int(x) for x in input().split()])
    print("Enter values for the Matrix B")
    b = []
    for i in range(n):
        b.append([int(x) for x in input().split()])
    c = []
    for i in range(n):
        c.append([a[i][j] * b[i][j] for j in range(n)])
    print("After matrix multiplication")
    print("-" * 7 * n)
    for x in c:
        for y in x:
            print(str(y).rjust(5), end=' ')
        print()
    print("-" * 7 * n)

运行如下：

    shiyanlou:~/ $ ./matrixmul.py                                        [23:45:24]
    Enter the value of n: 4
    Enter values for the Matrix A
    1 2 3 4
    5 6 7 8
    9 10 11 12
    13 14 15 16
    Enter values for the Matrix B
    16 15 14 13
    12 11 10 9
    8 7 6 5
