Program to find inverse of a matrix in Python

The program to find inverse of a matrix in python is as follows:

 

# Owner : TutorialsInhand Author : Devjeet Roy

import numpy as np

mat1 = [[11,32,13],
        [43,58,62],
        [75,81,92]]

matrix = np.array(mat1)

print("The inverse is:\n", np.linalg.inv(matrix))

The output of the inverse of a matrix in python program is as follows:

 

The inverse is:
 [[ 0.02181919 -0.13140157  0.08547009]
 [ 0.04822458  0.00257105 -0.00854701]
 [-0.06024599  0.1048572  -0.05128205]]

Few important tips about the program

1. To find the inverse of a matrix, we have used the numpy library in this case.

2. The numpy converts a nested list to a numpy array to perform computations.

3. The .linalg.inv() method takes care of the internal procdedures like finding determinant, multiplying with identity matrix and all that.
