Indeed, Sage has row_reduced_form for a polynomial matrix. The row reduced
form is sufficient to find a vector in the row space which has minimal
degree.
The method used to be called weak_popov_form, but that form is slightly
stronger and the algorithm does not compute it. Hence the warning.

I think it is: searching for weak_popov_form finds results in
matrix/matrix2.pyx with a method M.weak_popov_form(), though
admittedly the
Hi,
I don’t think this is implemented in Sage.
Cheers,
