Bring an (edit) matrix to reduced row echelon form.

Description

If E is a matrix, a matrix in reduced row echelon form is returned. If E is an editmatrix the equality part of E is transformed to reduced row echelon form. For an editset, the numerical part is transformed to reduced row echelon form.
