NumPy: Create a 4x4 matrix in which 0 and 1 are staggered, with zeros on the main diagonal
NumPy: Basic Exercise-30 with Solution
Write a NumPy program to create a 4x4 matrix in which 0 and 1 are staggered, with zeros on the main diagonal.
Sample Solution :
Python Code :
import numpy as np x = np.zeros((4, 4)) x[::2, 1::2] = 1 x[1::2, ::2] = 1 print(x)
[[ 0. 1. 0. 1.] [ 1. 0. 1. 0.] [ 0. 1. 0. 1.] [ 1. 0. 1. 0.]]
