Question

python

slove matrix inner product without numpy

A: 5x5 matrix, B: 5x5 matrix

(make array and use loop ?)  

Answer 1

Python Code:

Output:

Above code:

# Program to get inner product of two 5 x 5 matrix A and B using loops

# A matrix of the size 5x5

A = [[1,7,3,5,6],

[1,2,4,5,6],

[6,3,7,8,9],

[2,8,6,4,3],

[1,3,8,6,4]]

# B matrix of the size 5x5

B = [[4,8,1,2,7],

[6,7,3,2,2],

[4,1,2,1,8],

[1,2,4,4,8],

[4,6,8,6,8]]

# Ineer product result is matrix of the size 5x5

InnerProduct = [[0,0,0,0,0],

[0,0,0,0,0],

[0,0,0,0,0],

[0,0,0,0,0],

[0,0,0,0,0]]

# iteration through A's rows

for i in range(len(A)):

# iteration through B's columns

for j in range(len(B[0])):

# iteration through B's rows

for k in range(len(B)):

InnerProduct[i][j] += A[i][k] * B[k][j]

print("Inner Product Result is:")

for result in InnerProduct:

print(result)
