Implementing L In M3 in Python

Python is a popular programming language for implementing L In M3 due to its extensive libraries and ease of use. One of the most commonly used libraries for linear algebra in Python is NumPy. Below is an example of how to perform matrix multiplication using NumPy:

First, ensure you have NumPy installed. You can install it using pip:

pip install numpy

Here is a simple example of matrix multiplication:

import numpy as np

# Define two matrices
matrix_A = np.array([[1, 2], [3, 4]])
matrix_B = np.array([[5, 6], [7, 8]])

# Perform matrix multiplication
result = np.dot(matrix_A, matrix_B)

print("Matrix A:")
print(matrix_A)
print("Matrix B:")
print(matrix_B)
print("Result of Matrix Multiplication:")
print(result)

💡 Note: The np.dot function is used to perform matrix multiplication. Ensure that the dimensions of the matrices are compatible for multiplication.
