No, it is not hard to generate an identity matrix in Numpy using the inverse of multiple matrices of A. In fact, it is a common method to check if a matrix A is invertible or not. If the product of the inverse of multiple matrices of A gives an identity matrix, then A is invertible. Here's an example code snippet:
import numpy as np
# creating a Numpy array A
A = np.array([[2, 3], [4, 5]])
# finding the inverse of A
inv_A = np.linalg.inv(A)
# multiplying inverse of A with A to get identity matrix
identity = np.matmul(A, inv_A)
print(identity)
Output:
[[1. 0.]
[0. 1.]]
As we can see, we have generated an identity matrix using the inverse of matrix A.
