Matlab - Delaunay Triangulation and changing dimension

I have computed a 2-D Delaunay triangulation in Matlab R2010b: dt = DelaunayTri(x , y);

now, i want to add another dimension to dt, meaning adding Z cooridnate to every point. i know i can do it from the begining and by sending: dt = DelaunayTri(x , y , z), but i have my reasons.

how do i do it?

many thanks!

my intensions are taking the attached triangulation and strech it up, on the z axis.
