Try: M = matrix(QQ, [[1,1,1,1,1,1],[1,1,-2,1,1,-2],[-2,1,1,-2,1,1],[1,-2,1,1,-2,1]]) or M = matrix([[1/1,1,1,1,1,1],[1,1,-2,1,1,-2],[-2,1,1,-2,1,1], [1,-2,1,1,-2,1]]) > > --Mike > > -- > 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 > URL: http://www.sagemath.org > -- William Stein Professor of Mathematics University of Washington http://wstein.org -- 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 URL: http://www.sagemath.org
