Matrix algebra is a fundamental branch of mathematics that finds applications in various fields, including computer science, physics, economics, and engineering. University-level assignments often delve into complex topics, testing students' understanding of matrix operations and their ability to apply them programmatically. In this blog, we will explore a challenging matrix algebra assignment question, focusing on the implementation using programming. 

Assignment Question: Solving a System of Linear Equations

Consider the following system of linear equations:

Your task is to solve this system of equations using matrix algebra and programming. We'll guide you through the steps to ensure a comprehensive understanding.

Step-by-Step Guide: Solving the System Programmatically

1. Matrix Representation: Begin by representing the coefficients of the variables and the constants in matrix form. Let's create a coefficient matrix $A$ and a constant matrix $B$:

   [ 2 3 ]
   [ 4 -2 ]
    
   [ 7 ]
   [ 10 ]

2. Matrix Inversion: Next, find the inverse of matrix $A$, denoted as A^−1. This is crucial for solving the system of equations. If A^−1 exists, the solution is given by X=A^−1B.

3. Programming Implementation: Utilize a programming language, such as Python or MATLAB, to implement the matrix operations. For example, in Python, you can use libraries like NumPy to handle matrices efficiently. Ensure your code includes functions for matrix inversion and multiplication.

import numpy as np

A = np.array([[2, 3], [4, -2]])
B = np.array([[7], [10]])

A_inv = np.linalg.inv(A)
X = np.dot(A_inv, B)

print("Solution:", X)

​This code snippet uses NumPy to find the inverse of matrix $A$ and then calculates the solution $X$.

4. Interpretation of Results: The solution $X$ provides the values for variables $x$ and $y$ in the system of equations. In this case, the output might be , indicating that $x=2$ and $y=1$.
