Get the QR factorization of a given NumPy array

# Import numpy package
import numpy as np
# Create a numpy array 
arr = np.array([[10,22],[13,6]])
# Find the QR factor of array
q, r =  np.linalg.qr(arr)
# Print the result
print("Decomposition of matrix:")
print( "q=\n", q, "\nr=\n", r)

# Import numpy package
import numpy as np
# Create a numpy array 
arr = np.array([[0, 1], [1, 0], [1, 1], [2, 2]])
# Find the QR factor of array
q, r =  np.linalg.qr(arr)
# Print the result
print("Decomposition of matrix:")
print( "q=\n", q, "\nr=\n", r)

# Import numpy package
import numpy as np
# Create a numpy array 
arr = np.array([[5, 11, -15], [12, 34, -51],
                [-24, -43, 92]], dtype=np.int32)
# Find the QR factor of array
q, r = np.linalg.qr(arr)
# Print the result
print("Decomposition of matrix:")
print( "q=\n", q, "\nr=\n", r)
