That's not true for the 1x2 matrix [1,0]: sage: matrix(1,2,[1,0]).right_kernel() Free module of degree 2 and rank 1 over Integer Ring Echelon basis matrix: [0 1] The basis matrix is not of the form [I|A], for I the identity matrix. For a *random* matrix you'll get [I|A] though. William William > > -- > --------------------------------------------------------------------- > MSc.
