Why I cannot pointplot3d?:Comments#answer80452 Hi, I am sure that other Maple users might suggest other methods to make this faster but you might want to try the following: restart; with(ArrayTools): x := Array([1, 2, 3]): y := Array([1, 2, 3]): zxy := NULL; for i to 3 do for j to 3 do zxy := Concatenate(1, zxy, (Vector[row])([x[i]+y[j], x[i], y[j]])): end do: end do: zxy; with(plots): pointplot3d([seq([zxy[l, 1], zxy[l, 2], zxy[l, 3]], l = 1 .. 9)], color = red, axes = normal); I believe this will run better and will give you an zxy that has the three rows for z,x,y in that order.
