Yeah, that is my opinion too. However I disagree a little here about the degree of zero polynomial. I would expect SylvesterMatrix(x^2, 0) To be [0 0] [0 0] rather than a ValueError ( If I take the degree of zero to be - Infinity) or [0] (If I take the degree of zero to be -1) -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
