▷Gauss Jordan Elimination / Row Echelon – Step by Step – using the TiNSpire CX

Gauss Jordan Elimination is a pretty important topic in Linear Algebra.

So, it would be great to see steps when performing the procedure, also called Reverse Row Echelon method. It seems there is a continental divide in its proper naming.

Once you can pull out your handy TiNspire and launch the Linear Algebra Made Easy app from www.tinspireapps.com just enter your matrix as shown below:

Notice that first the forward Gauss Elimination Method is performed, aka Row Echelon Method.

Lastly, the Reverse Row Echelon Method gives the final solution, which appears in the most right column. Voila.
