A Gauche perspective on row reduced echelon form and its uniqueness

General Mathematics 2021-04-16 v3

Abstract

Using a left-to-right "sweeping" algorithm, we define the \emph{Gauche basis} for the column space of a matrix MM. By means of the Gauche basis we interpret the row reduced echelon form of MM, and give a direct proof of its uniqueness. We conclude with pedagogical reflections.
