I'm not sure how to avoid using lambda with a piecewise-defined function like yours, although Kelvin Li gives a perfectly good answer to your question. With more simply defined functions, you can work like this: sage: H(x,y) = sin(x)*sin(y) sage: plot(H.substitute(y=3), (x, 0, 10)) sage: H.substitute(y=3) (x, y) |--> sin(3)*sin(x) (I couldn't get h(x, y) = Piecewise(...) to work.) -- John -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
