Here is a Python code to code adjacency matrix

import numpy as np

def code_adjacency_matrix(adjacency_matrix):
    """
    This function takes an adjacency matrix and returns a list of lists
    of integers.
    """
    adjacency_matrix = np.array(adjacency_matrix)
    adjacency_matrix = adjacency_matrix.tolist()
    adjacency_matrix = [[int(x) for x in y] for y in adjacency_matrix]
    return adjacency_matrix

# Creating a matrix
adjacency_matrix = np.array([[0, 1, 0], [1, 0, 1], [0, 1, 0]])

# Calling the function
print((code_adjacency_matrix(adjacency_matrix)))

#Example Output
# [[0, 1, 0], [1, 0, 1], [0, 1, 0]]

#Remember to inspect code for bugs.
