I am wondering about the relation betwen RRE forms and identity matrices. Consider the reduced row echelon form of any square matrix. Must this reduced row echelon form of the matrix necessarily be an identity matrix?(adsbygoogle = window.adsbygoogle || []).push({});

I would suppose yes, but can this fact be proven? Could anyone provide an outline of the proof, or provide the link? Thanks much.
