them, so I need a `echelon_matrix_iterator`. Whether it is cython or not
is a matter of micro seconds, so I do not care that much (except that
using cython allows to set the cache of matrices with the pivot that can
be used later).

where it was the code was written to output vector spaces and I do not
want to deal with them. So it was the only way to go.
