Applications of Linear Algebra for Practical Problem Solving

Many modern technologies rely on linear algebra, yet traditional textbooks often focus on abstract proofs rather than real-world utility. This text-based course bridges the gap by showing you how to apply matrix equations, vector spaces, and linear transformations to solve concrete problems in engineering, data analysis, and computer science. You will start with the fundamental definitions and terminology before moving on to practical applications. By reading through structured explanations and analyzing code-based mathematical models, you will gain the confidence to implement algebraic concepts in your daily work. What you will learn: Understand the core concepts of vectors, matrices, and systems of linear equations; Apply matrix factorization techniques to compress data and extract key features; Implement linear regression models from scratch using matrix operations; Use eigenvalues and eigenvectors to analyze network graphs and dimensional reduction; Explore modern applications including basic recommender systems and image transformations. This course begins with essential terminology and foundational algebraic structures, then guides you step-by-step through practical implementations in data science and beyond. It is designed for beginners who want a clear, conceptual understanding of linear algebra without needing a background in advanced mathematics.
