# How to Calculate Determinant of a Matrix or ndArray?

This recipe helps you Calculate Determinant of a Matrix or ndArray

0

## Recipe Objective

Do you find calculating determinant of a matrix is easy? Have to tried to find it using python.

So this is the recipe on how we can Calculate Determinant of a Matrix or ndArray.

## Step 1 - Importing Library

``` import numpy as np ```

We have only imported numpy which is needed.

## Step 2 - Creating Matrix

We have created two matrix of which we will find determinant. ``` matrixA = np.array([[1, 2, 3, 23], [4, 5, 6, 25], [7, 8, 9, 28], [10, 11, 12, 41]]) matrixB = np.array([[2, 3, 4], [5, 6, 9], [7, 8, 1]]) ```

## Step 3 - Finding determinant

We will finding determinant by using the function np.linalg.det to find the determinant of both the matrix ``` print(np.linalg.det(matrixA)) print(np.linalg.det(matrixB)) ``` So the output comes as

```-4.862776847858206e-15
