Take a look at this here: sage: A = matrix(QQ, 3, [0,1,2,1,1,3,-1,0,-1]) sage: A
[ 0 1 2] [ 1 1 3] [-1 0 -1] sage: A.kernel() Vector space of degree 3 and dimension 1 over Rational Field Basis matrix: [ 1 -1 -1] sage: Perhaps I'm just completely dumb but this vector is not contained in the kernel of A. My SAGE version is: sage: version() 'SAGE Version 3.0, Release Date: 2008-04-21' --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
