## Program Code – Matrix Manipulation: Unveiling the Mystery of Matrix Inversion

```
``````
import numpy as np
def find_matrix_inverse(matrix):
'''
This function finds the inverse of a given matrix.
Parameters:
matrix (np.array): A numpy array representing the square matrix whose inverse is to be found.
Returns:
np.array: The inverse of the given matrix if it exists. Otherwise, returns None.
'''
# First, we check if the matrix is square
if matrix.shape[0] != matrix.shape[1]:
print('Matrix must be square!')
return None
# Checking if the matrix is invertible by ensuring the determinant is not zero
det = np.linalg.det(matrix)
if det == 0:
print('Matrix is singular and cannot be inverted.')
return None
# If the matrix is square and invertible, calculate the inverse
inv_matrix = np.linalg.inv(matrix)
return inv_matrix
# Example usage
if __name__ == '__main__':
# Creating a sample matrix
sample_matrix = np.array([[4, 7], [2, 6]])
inverse_matrix = find_matrix_inverse(sample_matrix)
if inverse_matrix is not None:
print('Inverse of the sample matrix is:
', inverse_matrix)
```

### ### Code Output:

```
Inverse of the sample matrix is:
[[ 0.6 -0.7]
[-0.2 0.4]]
```

### ### Code Explanation:

In this program, we’re unfolding the mystery behind Matrix Inversion, which, let’s face it, sounds way cooler than it might initially seem.

First off, we import `numpy`

, a hugely popular Python library for all things matrix and array. It’s like the Swiss Army knife for data scientists and engineers who dabble in the mystical arts of number crunching.

Next, crawl into the belly of the beast with the `find_matrix_inverse`

function. It’s straightforward yet robust, designed to tackle square matrices and check if they’re up for the inversion challenge. Here’s how it rolls:

**The Squareness Check**: The road to inversion is paved with square matrices. If the matrix cheekily tries to sidestep this fundamental law by not being square, we straightaway show it the door with a polite, yet firm, ‘Matrix must be square!’.**The Determinant Duel**: Not every square matrix has the guts to face inversion. If its determinant cowers to zero, the matrix is what we call ‘singular’ – a fancy term for “Sorry, buddy, you’re not going anywhere.” We gently break the news that it can’t be inverted.**The Inversion Incantation**: For the brave matrices that have made it this far, it’s time to pull the rabbit out of the hat. Using`np.linalg.inv()`

, invincibility—oops, I mean inversion—is achieved. It magically turns the matrix into its inverse, a feat akin to pulling off a double backflip in the matrix world.

The pièce de résistance is the `if __name__ == '__main__':`

part, where we put this whole circus to test with an example matrix. It’s like the final act where the magician (that’s us) reveals the trick, and the audience (also us) gasps in astonishment at the sight of its inverse majestically displayed.

Random fact: Did you know matrices have been around since around 200 BC? They were used in ancient China for solving linear equations. Fast forward a couple of millennia, and here we are, still fascinated, still solving (but with a bit more flair).

In conclusion, what we’ve got here is not just code. It’s an adventure into the heart of matrices, unearthing the magic of inversion. So, next time you’re stuck inverting a matrix, remember: it’s not just math; it’s a journey. Thanks for being part of it. Keep coding, and keep exploring the mysteries of the universe! ✨
