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.

Python3 1== `

import the important module in python

import numpy as np

make matrix with numpy

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

applying matrix.diagonal() method

geeks = gfg.diagonal()

print(geeks)

`

Example #2 :

Python3 1== `

import the important module in python

import numpy as np

make a matrix with numpy

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

applying matrix.diagonal() method

geeks = gfg.diagonal()

print(geeks)
