reduced echelon form
Any matrix can be transformed to a unique matrix in reduced echelon form using elementary row operations, by Gauss–Jordan elimination. The solutions of a system of linear equations can be immediately obtained from the reduced echelon form to which the augmented matrix has been transformed.
