import numpy as np

def toBit(x):
        if x<= 0:
            x = 0               
        else:
            x = 1
        return x

VtoBit = np.vectorize(toBit)

arr1 = np.random.randn(6,10)
arr2 = VtoBit(arr1)

print(arr2)

Generate a random matrix with binary values:

import numpy as np
row, col = 10, 5
matrix = np.random.randint(2, size=(row,col))
