Voronoi Edges Weight value

Hi i'm a matlab newbie , i follow these instructions http://www.mathworks.com/help/techdoc/math/bspqjqq-1.html to create a diagram for some set of points , and all works fine , now i need to add a value for each Voronoi Edge called Weights equal to its minimum distance from the closest point or sites.

can u write me an example code for that
