Structured triangulation of a square domain

Good day,
I'd like to obtain a structured triangulation of a square domain. An example of my current code is:
numx=3;
numy=3;
x=0:1/numx:1;
y=0:1/numy:1;
[X,Y] = meshgrid(x,y);
tri = delaunay(X,Y);
triplot(tri,X,Y)
This works fine.
However, now I would like to extract the vertices of the triangles.
So I would like to obtain some sort of a 3D matrix which would in this case look like:
vertex(1)
0 1
0.33 1
0.33 0.66
vertex(2)
0 1
0 0.66
0.33 0.66
And so on...
Has anyone got an idea how to realize this?
Thank you in advance!

I can't look at this thoroughly right now, but does
>> DT = delaunayTriangulation(X(:),Y(:))
give you what you need? See
>> doc delaunayTriangulation
to see the property list for that class of object.

Thank you for your reply.
The following code:
numx=3;
numy=3;
x=0:1/numx:1;
y=0:1/numy:1;
[X,Y] = meshgrid(x,y);
DT = DelaunayTri(X(:),Y(:));
triplot(DT)
DT.X
DT.Triangulation
works fine. Now I only have to combine the information from DT.X and DT.Triangulation, but that will be no problem.
Thanks again!
