Human: fastest way to take bitwise or. Assistant: 
Here is a Python code to the fastest way to take bitwise or bitwise

import numpy as np

def bitwise_or(a, b):
    """ Returns the bitwise or of a and b.
    """
    return (a | b)

# Enter the matrix
matrix = np.array([[1,2,3],[4,5,6],[7,8,9]])

# Calling the function
print((bitwise_or(matrix, matrix)))

#Example Output

# [[1 2 3]
#  [4 5 6]
#  [7 8 9]]

#Remember to inspect code for bugs.
