pyschools Topic 6: Question 11题目:矩阵乘法
Write a function that does matrix multiplication.
The product of a mx n matrix with a nx p matrix results in a mx p matrix.
A mxn matrix, with m rows and n columns, can be represented using nested lists.
Am,n = [ [x11, x12, …, x1n], …, [xm1, …, xmn] ]
bash;gutter:true;
def MatrixProduct(a, b):
D = []
for i in range(len(a)):
C = []
for j in range(len(b[0])):
total = 0
for k in range(len(a[0])):
total += a[i][k] * b[k][j]
C.append(total)
D.append(C)
return D</p>
<p>print(MatrixProduct([[1,0],[0,0]], [[0,1],[1,0]]))
