Thanks for the answers! Both plot3d(floor(min_symbolic(x, y)),(x,1,7),(y,1,7))

and plot3d(lambda a, b: floor(min(a, b)),(x,1,7),(y,1,7)) produce the right plot.

`I wonder whether the result of ?min might mention the existence of`

`min_symbolic, and similarly for max. When the first attempt failed, I`

`looked at what ?min said, and didn't get much out of it. Had it`

`mentioned "see also min_symbolic" or something of the kind, that would`

`have been a clue.`

If you care aboutperformance, there may be a difference between using min_symbolic andusing a "lambda" argument to plot. You'd need to try to see which oneis faster for your application.--You received this message because you are subscribed to the GoogleGroups "sage-support" group.To unsubscribe from this group and stop receiving emails from it, sendan email to sage-support+unsubscr...@googlegroups.com.To view this discussion on the web visithttps://groups.google.com/d/msgid/sage-support/fa9069b8-b7c7-4ef8-89b6-49e440673e55n%40googlegroups.com<https://urldefense.com/v3/__https://groups.google.com/d/msgid/sage-support/fa9069b8-b7c7-4ef8-89b6-49e440673e55n*40googlegroups.com?utm_medium=email&utm_source=footer__;JQ!!P_zEGVH0kSMiWA!BefAaie66ByebM3xfGhIykFkogDnP59VtSVuweXCOI1rGL7VPlTzJhDBa28OVJI_avHcoN0d1ZtnAyOpTA$>.
