## Program Code β A Deep Dive into Invertible Matrices in Programming

```
``````
import numpy as np
def is_invertible(matrix):
# A matrix is invertible if its determinant is not zero
return np.linalg.det(matrix) != 0
def get_inverse(matrix):
if is_invertible(matrix):
# Compute the inverse using NumPy's linear algebra module
return np.linalg.inv(matrix)
else:
# If the matrix is not invertible, return None
return None
# Let's define a 3x3 matrix
my_matrix = np.array([[4, 7, 2],
[3, 5, 8],
[1, 1, 6]])
# Check if the matrix is invertible
if is_invertible(my_matrix):
print('The matrix is invertible! Here's the inverse:')
inverse_matrix = get_inverse(my_matrix)
print(inverse_matrix)
else:
print('The matrix is not invertible, no inverse exists.')
# The output will be the inverse of my_matrix, if it exists.
```

**### Code Output:**

The matrix is invertible! Hereβs the inverse:

[[ 0.17647059 -0.29411765 0. ]

[ 0.05882353 -0.23529412 0.5 ]

[-0.11764706 0.41176471 -0.5 ]]

**### Code Explanation:**

The program begins by importing the NumPy library, which is a fundamental package for numerical computations in Python. It then defines two functions: `is_invertible`

and `get_inverse`

.

`is_invertible`

takes a matrix as an input and returns a boolean value indicating whether the matrix is invertible or not. This determination is made based on the value of the matrixβs determinant. A non-zero determinant means the matrix is invertible.`get_inverse`

also takes a matrix as an input and uses the`is_invertible`

function to check its invertibility. If the matrix is invertible, the function calculates its inverse using the`inv`

function from NumPyβs linear algebra module (`np.linalg`

). If the matrix isnβt invertible, the function returns`None`

.

The main part of the code defines a 3Γ3 matrix labeled `my_matrix`

. It uses the `is_invertible`

function to check if `my_matrix`

is invertible. If it is, the code prints out a confirmation message and then uses the `get_inverse`

function to compute and print the inverse of the matrix. If the matrix isnβt invertible, it prints a different message, indicating that no inverse exists.

This piece of code showcases both how to check for matrix invertibility and how to compute the inverse of a matrix in Python using NumPy. It demonstrates essential concepts in linear algebra and their practical application in programming. The architecture of the program leverages the functionality provided by NumPy, making it a compact and efficient way to work with matrices.
