1.3.3 Gauss-Jordan Elimination Gauss-Jordan elimination is a variation of Gauss elimination in
which the elements above the major diagonal are eliminated (made zero)
as well as the elements below the major diagonal. The A matrix is
transformed to a diagonal matrix. The rows are usually scaled to yield
unity diagonal elements, which transforms the A matrix to the identity
matrix, I. the transformed b vector is the solution vector x.
