delaunayTriangulation object from existing triangulation

Hi all,

I have an existing triangulation (vertices x and y and connectivity matrix tri) and I would like to apply the PointLocation method of the delaunayTriangulation class on this existing triangulation (much like the obsolete tsearch function in older versions of matlab).

However, the PointLocation method obviously needs a delaunayTriangulation instance as input. The delaunayTriangulation class always seems to perform its own triangulation procedure, which results in a different connectivity matrix than the tri matrix that I have given the vertices x and y.

Is there a way to apply PointLocation (or something like tsearch) to my existing triangulation? I have Matlab 2013a.

Cheers,

Max
