Does MATLAB duplicate data when using DelaunayTri, TriRep, etc?

Say I want to mesh some (x,y) points.

If I use delaunay() then I just get one new piece of data, the triangulation, tri.

However, if I use DelaunayTri, I'll get a structure containing the points and the triangulation.

Does this mean the points have been duplicated in memory? Isn't this a bit wasteful especially if you have a large set of x,y?

Similarly say I have x,y,tri already and want to use some of the TriRep methods. If I use TriRep() does this duplicate the points AND the triangulation?

Hi

By duplication if you mean a new structure created by TriRep will be having the a copy of the input besides the new triangulation data, yes it does.
