Inverse Matrix by Gauss-Jordan Elimination | Linear Algebra

Показать описание
We introduce a simple inverse matrix algorithm. We find an inverse matrix using Gauss Jordan elimination. By converting a matrix to its reduced row echelon form, we can simultaneously convert an identity matrix into the inverse. We will use an augmented matrix and a sequence of elementary row operations to perform this process. We also see an example of applying this algorithm to a non-invertible matrix. #linearalgebra

I went another way and ended up in the second examlpe with R1: 12/3 -15/3 -6/3 R2:15/3 -18/3 -6/3 R3: -8 9 3 Just needed to break down my result though.

Inverse matrix? More like "Interesting, and makes sense!"
