NumPy: Compute the sum of the diagonal element of a given array

NumPy: Linear Algebra Exercise-15 with Solution

Write a NumPy program to compute the sum of the diagonal element of a given array.

Sample Solution:

Python Code :

import numpy as np
m = np.arange(6).reshape(2,3)
print("Original matrix:")
print(m)
result =  np.trace(m)
print("Condition number of the said matrix:")
print(result)

Sample Output:

Original matrix:
[[0 1 2]
 [3 4 5]]
Condition number of the said matrix:
4
