How to find determinant and Inverse matrix of an array using scipy in python?


To write a small piece of code for finding determinant and Inverse matrix using python scipy library.

Input :

2 dimensional array.


Determinant of 2D array.
Inverse matrix.

  Define a sample array.

  Import linear algebra attributes from scipy.

  Pass to the det() constructor.

  Finds the determinant of an two dimensional array.

from scipy import linalg

import numpy as np

#define a 2-dimensional array

sample_array = np.array([[1,2],[3,4]])

#pass values to det() function

print(“Determinant of array”)

d = linalg.det(sample_array)


#Inverse matrix of array

print(“Inverse matrix of array”)

I = linalg.inv(sample_array)
