This recipe helps you Calculate Trace of a Matrix

This python source code does the following: 1. Creates your own numoy matrix 2. Calculates trace of the given matrix

In [1]:

```
## How to Calculate Trace of a Matrix
def Kickstarter_Example_7():
print()
print(format('How to Calculate Trace of a Matrix', '*^72'))
# Load library
import numpy as np
# Create matrix
matrix = np.array([[1, 2, 3],
[4, 5, 6],
[7, 8, 9],
[10, 11, 12]])
# Calculate the tracre of the matrix
print()
print('Calculate the tracre of the matrix: ',
matrix.diagonal().sum())
