Linear Algebra 4: Matrix Equations

Solving matrix equations Ax= b

Preface

Welcome back to the fourth edition of my ongoing series on the basics of Linear Algebra, the foundational math behind machine learning. In my previous article, I introduced vectors, linear combinations, and vector spans. This essay will take a look at the matrix equation Ax = b and we’ll see how the very principle of solving a system of linear equations is linked to the matrix equation.
