Thanks. I was basically looking for confirmation that I hadn't overlooked something in the documentation. The transposition of the first two dimensions, compared to their interpretation in Plot3D, is something that I think ought to be mentioned explicitly as the second item in the Details section of the documentation, imediately after In ListPlot3D[array], array must be a rectangular array. Each element can be either a single real number representing a z value, or an {x,y,z} triple. ----- Tomas Garza <tgarza10 at msn.com> wrote: > The explanation lies in how Table constructs the array. > The definition in the Help browser says > > Table[expr,{i,Subscript[i, min], Subscript[i, max]}, > {j,Subscript[j, min], Subscript[j, max]}, ] gives a nested list. > The list associated with i is outermost. > > This is, I agree, contrary to what happens with a double integral, > where the inner integral goes first.
