如何用函数求python非方阵矩阵内所有元素的N次方！非常感谢~

Answer 1

可以原生Python实现

def matrix_power(matrix, power):
    result = []
    for row in matrix:
        new_row = []
        for element in row:
            new_row.append(element ** power)
        result.append(new_row)
    return result

你还可以借助第三方库函数，比如numpy

import numpy as np

matrix = [[1, 2, 3], [4, 5], [6, 7, 8, 9]]
power = 2

result = np.power(matrix, power)
