About this document
Understanding Matrix Rank and Inverses by Prolay is a document available to read on EtoBox.
This document discusses the rank of a matrix and how it relates to the solvability of systems of linear equations. It begins by defining the rank of a matrix as the dimension of the range of the left-multiplication transformation. It then proves several theorems about how the rank is preserved under elementary row/column operations and relates the rank to the invertibility of a matrix. The document concludes by stating theorems about how the rank determines whether a homogeneous or non-homogeneous system of
