Vector Equations and Spans — Preface Welcome back to the third essay of my ongoing series on the basics of Linear Algebra, the foundational math behind machine learning. In my previous article, I walked through the echelon matrix forms. This article will take a look at vectors, spans and linear combinations and connect these new ideas…

Row echelon form and reduced row echelon form — Preface Welcome back to the second essay of my ongoing series on the basics of Linear Algebra, the foundational math behind machine learning. In my previous article, I introduced linear equations and systems, matrix notation, and row reduction operations. This article will walk through the echelon…

Systems of linear equations — Preface This is the first addition to what will become an ongoing series on the basics of Linear Algebra, the foundational math behind machine learning. This article would best serve readers if read in accompaniment with Linear Algebra and Its Applications by David C. Lay, Steven R…
