echelon: 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.Usage
