Here is a Python program to gradient the l2 norm in 2d

import numpy as np

def grad_l2_norm(x, y):
    """Gradient of the l2 norm in 2D."""
    return (2*x, 2*y)

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

# Calling the function
print((grad_l2_norm(array[0][0], array[0][1])))

#Example Output
# (2, 4)

#Remember to inspect code for bugs.
