Solution

To perform matrix multiplication on numpy arrays A and B, you can use the np.dot(A, B) function. Here are the steps:

Import the numpy library:

import numpy as np

Define your matrices A and B. For example:

A = np.array([[1, 2], [3, 4]])
B = np.array([[5, 6], [7, 8]])

Use the np.dot() function to multiply the matrices:

result = np.dot(A, B)

Print the result:

print(result)

Note: A+B and AB are not matrix multiplications. A+B is matrix addition and AB is element-wise multiplication.
