How to create triangulated surface using data points (x,y,z)

I have set of points in 3D (x,y,z) in Cartesian coordinates.
I would like create surface mesh (in terms of finite element modeling) of these points.
I tried using DelaunayTri, but that gives me tetrahedral and not triangles, which I want.
Thanks Prab

Hello Prabh, I have the same problem. If you had solution. Can you please discuss?

Hi Prab,
I think you are looking for the convex hull? So take a look at convhulln or convexHull (depending on your MATLAB version).

Hi Prab,
O.K., I understand. Can you use two coordinates only? E.g. x and y only, build the (2D) triangulation and then plot/analyze the triangles in 3D? If this is not directly possible, you might have the chance to rotate all points by a rotation matrix and then use 2D triangulation.
