矩陣相乘
Example Code

import numpy as np

martixA = np.arange(9).reshape((3,3))

martixB = np.arange(9).reshape((3,3))

print('martixA = martixB = ')

print(martixA)

print('martixA product martixB = ')

print(np.matmul(martixA, martixB))

Note and Comments

import numpy as np: 讀入numpy函式庫並命名為np

np.arange(l).reshape((m,n)) 生成一個有l個元素的陣列, 並重新將此陣列重新分割爲m*n的矩陣

np.matmul(martixA, martixB) 矩陣相乘
