Find Matrix Multiplication
In the following example, we will multiply the two given matrices (two-dimensional arrays).
Example
Python Compiler
arr1 = [
[1, 1, 1],
[1, 1, 1],
[1, 1, 1]
]
arr2 = [
[2, 2, 2],
[2, 2, 2],
[2, 2, 2]
]
arr3 = [[0]*3 for _ in range(3)]
print("Matrix A (3 x 3):")
for i in range(0, 3):
for j in range(0, 3):
print(arr1[i][j], end=" ")
print()
print("\nMatrix B (3 x 3):")
for i in range(0, 3):
for j in range(0, 3):
print(arr2[i][j], end=" ")
print()
for i in range(0, 3):
for j in range(0, 3):
for k in range(0, 3):
arr3[i][j] = arr3[i][j] + arr1[i][k] * arr2[k][j]
print("\nMatrix Multiplication (A x B):")
for i in range(0, 3):
for j in range(0, 3):
print(arr3[i][j], end=" ")
print()
Output
Matrix A (3 x 3):
1 1 1
1 1 1
1 1 1
Matrix B (3 x 3):
2 2 2
2 2 2
2 2 2
Matrix Multiplication (A x B):
6 6 6
6 6 6
6 6 6
