Hello everyone,
I'm having a lot of problems about extracting edges from a random Voronoi tessellation.
Would any of you know how? Is there any function that allows you to do this?
Thank you.

Hi,
can you specify what you mean by "a random voronoi tesselation"?
Are you creating a 3D voronoi tesselation and trying to extract its edges?If so, Using voronoin /VoronoiDiagram functions output arguments,
[v,c]= voronoin(P); % P is matrix with coordinates
returns matrix v which represent Vertices of edges and a cell array c where each element of c containes the row indices of the Voronoi vertices v that make up a Voronoi cell.
v(c{i},:)
would return the vertices corresponding to cell number 'i'
You can refer to this Computing the Voronoi Diagram for more insight
Hope this helps!
