np.inner() np.outer()向量的內外積
Example Code

import numpy as np

vectorA = [1,2,3]

vectorB = [0,5,10]

print('vectorA = ', vectorA)

print('vectorB = ', vectorB)

print('dot product of vectorA & vectorB =', np.dot(vectorA, vectorB))

print('inner product of vectorA & vectorB =', np.inner(vectorA, vectorB))

print('outer product of vectorA & vectorB =')

print(np.outer(vectorA, vectorB))

Note and Comments

import numpy as np: 讀入numpy函式庫並命名為np

np.dot(A, B): A,B兩向量的點積

np.inner(A, B): A,B兩向量的內積

np.outer(A, B): A,B兩向量的外積

result

inner product & outer product; 向量的內外積
