numpy.triu() in Python

Python | Numpy np.triu_indices

Last Updated : 30 Jan, 2020

With the help of np.triu_indices() method, we can get the indices for the upper triangle of an [n, m] array by using np.triu_indices() method.

Syntax : np.triu_indices(n, m) Return : Return the indices for the upper triangle.

Example #1 : In this example we can see that by using np.triu_indices() method, we are able to get the indices for the upper triangle of an [n, m] array by using this method.

Python3 1=1

# import numpy and triu_indices
import numpy as np

# using np.triu_indices() method
gfg = np.triu_indices(2, 3)

print(gfg)

Output :

(array([], dtype = int64), array([], dtype = int64))

Example #2 :

Python3 1=1

# import numpy and triu_indices
import numpy as np

# using np.triu_indices() method
gfg = np.triu_indices(4)

print(gfg)

Output :

array([], dtype = int64)
