Comment:
- Perhaps a very short statement about what the row echelon form of
matrices over fields look like would be nice.
- line 4035: instead of echelon_form, I think this should be
``echelon_form`` or :meth:`echelon_form`
- line 4085: I'd prefer if this was done in two lines
{{{
F = R.fraction_field()
return self.change_ring(F).echelon_form()
}}}
so that if an error occurs when creating the fraction field, the line
number corresponds to the obvious problem. (Of course, this would be
clear from the traceback anyway...)
