looking at the code in ticket 7458 (link:http://trac.sagemath.org/ sage_trac/attachment/ticket/7458/sylvester.patch)
ive tried to calculate the sylvester matrix of a given f and g (polys of (x,a)) and its deteminant (with respect to a) with the following code R.<x,a> = PolynomialRing(ZZ) f = x^5 + 3*x^4 - 2*x^3 - 3*x^2 - a*x - 5 g = x^5 + 7*x^4 - 5*x^3 + a*x^2 + x - 8 M = f.sylvester_matrix(g,x) print M syldet=f.sylvester_matrix(1 + g, x).determinant() det=M.determinant() print syldet print det however sage doesnt seem to recognise the sylvester_matrix command any help -- 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
