# How to Calculate Trace of a Matrix?

This recipe helps you Calculate Trace of a Matrix

0

## Recipe Objective

Calculating trace of matrix isn"t easy but have you tried to do it in python?

So this is the recipe on how we can Calculate Trace of a Matrix.

## Step 1 - Importing Library

``` import numpy as np ```

We have only imported numpy which is needed.

## Step 2 - Creating Matrix

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

## Step 3 - Calculating Trace of Matrix

We know that the trace of a matrix is calculated by summing the values of diagonals. So we have done the same to find the trace. ``` print("Calculate the tracre of the matrix: ", matrix.diagonal().sum()) ``` So the output comes as

```Calculate the tracre of the matrix:  15
```
