Supplemental material for math papers

Paper:

Two direct solvers for a system of linear equations

Supplements:

Here is a one-page overview of the row space in situ algorithm.  This is an easier to read version than what appears in the original article.  It gives a more intuitive derivation.
 

This file contains some 3-by-3 examples for the row space in situ algorithm.
It also includes an example for the online version.

This file contains some 3-by-3 examples for the column space in situ algorithm.
It also includes an example for the online version.  There are also a few

suggested exercises for instructors.

On Github  is a Python implementation of the algorithms.
