it is the matter of adding extra zero rows or columns to the matrix you want to decompose. This could be a quick fix. (in reference to computing LU decompositions of non-square matrices) -- in a numerical setting, adding extra zero rows/columns may not be such an attractive option: if previously you know you had a maximal rank matrix, you have now ruined it by the padding. It's worth checking the documentation and literature if padding is appropriate/desirable for the target algorithm/implementation. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
