Python | Numpy matrix.diagonal() (original) (raw)

Last Updated : 12 Apr, 2019

With the help of **Numpy matrix.diagonal()** method, we are able to find a diagonal element from a given matrix and gives output as one dimensional matrix.

Syntax : matrix.diagonal()

Return : Return diagonal element of a matrix

Example #1 :
In this example we can see that with the help of matrix.diagonal() method we are able to find the elements in a diagonal of a matrix.

import numpy as np

gfg = np.matrix( '[6, 2; 3, 4]' )

geeks = gfg.diagonal()

print (geeks)

Example #2 :

import numpy as np

gfg = np.matrix( '[1, 2, 3; 4, 5, 6; 7, 8, 9]' )

geeks = gfg.diagonal()

print (geeks)
