Recipe Objective

Have to tried to calculate diagonal elements and sum of diagonal values.

So this is the recipe on how we can calculate Diagonal of a Matrix.

Step 1 - Import the library

import numpy as np

We have only imported numpy which is needed.

Step 2 - Creating a matrix

We have created a matrix on which we will perform the operation. matrix = np.array([[1, 2, 3, 23], [4, 5, 6, 25], [7, 8, 9, 28], [10, 11, 12, 41]])

Step 3 - Finding elements

We can find diagonal elements by the function diagonal and by using sum function we can find the sum of the elements. print(matrix.diagonal()) print(matrix.diagonal().sum()) So the output comes as

[ 1  5  9 41]
