list of edges and triangles connecte to each edge

% Edges(i,:)= nodes forming edge i

% T(i,:)= list of triangles connected to edge i

In what format is your data stored?

Is it a delaunayTriangulation?

A triangulation?

A graph or digraph network object?

A plain text file (in which case, in what format is the data stored in the file)?

An N-by-2 or N-by-3 set of point coordinates that you want to triangulate?

it is a delaunayTriangulation.

Hi Ahmad,

To find the list of edges use the command

Edges = edges(TR)

To find the list of triangles use the command

T = edgeAttachments(TR,startIndex,endIndex)

For further information check the Delaunay Triangulation Object in the link below:
