Not sure why this isn't documented, but try sage: plot3d(g(x,y),(x,-5,5),(y,-5,5),plot_points=200) or whatever you need. It should go reasonably fast on a reasonably modern computer. - kcrisman -- 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
