How to Solve a Kirchhoff's Rules Problem - Matrix Example

Published on 21 May 2018 / In Science & Technology

Oh, all those numerous and nasty equations!
All the plugging and chugging, it takes too much patience.
I've got just the thing for such an awful occasion:
It's mighty, it's sleighty! It's Gauss-Jordan Elimination!

First, our equations enjoy preparation.
Each variable is queued in ascending gradation.
Once aligned and accounted, their nice numeral agents,
Get bumped to a matrix in corresponding locations.

Next, we apply a few matrix operations:
Addition and subtraction. Division, multiplication.
Yes, our rows are massaged with arithmetication,
Until they're reduced to the simplest notation.

Lo', all of our multiplex math manueveration,
Concludes with a comely, concise configuration.
The name of this sexy and subtle sophistication?
She goes by Row Reduced Echelon Formation.

To the left: a delightful diag-one-alation.
To the right: our solutions, in column notation.
Such a time-saving tool! Such a cool calculation!
It's mighty, it's sleighty! It's Gauss-Jordan Elimation!
