I have one question related to terminology. The command echelon form seems to produce the reduced row echelon form. Isn't row echelon form something like matrix([[1,1,1],[0,1,1], [0,0,1]]) ? I think that this is confusing in Sage. Or are in English "row echelon form" and "reduced row echelon form" equivalent?
