Answer

Here you go:

import numpy as np
# create random adjacency matrix
A = np.random.randint(0,2,(10,10))
A[np.arange(10),np.arange(10)] = 1
# save to .txt file
filename='adjacency_matrix.txt'
np.savetxt(filename,A)

JavaScript
 
import numpy as np
# create random adjacency matrix
A = np.random.randint(0,2,(10,10))
A[np.arange(10),np.arange(10)] = 1
# save to .txt file
filename='adjacency_matrix.txt'
np.savetxt(filename,A)
