NumPy: Linear Algebra Exercise-12 with Solution
Write a NumPy program to compute the inverse of a given matrix.
Sample Solution :
Python Code :
import numpy as np m = np.array([[1,2],[3,4]]) print("Original matrix:") print(m) result = np.linalg.inv(m) print("Inverse of the said matrix:") print(result)
Original matrix: [[1 2] [3 4]] Inverse of the said matrix: [[-2. 1. ] [ 1.5 -0.5]]
