Computing the Voronoi Diagram This example shows how to compute a 2-D and 3-D Voronoi diagram. voronoin) gives two outputs: [vornb,vorvx], one for the vertices and another one for the cells. This script uses the work of Park* to generate a Voronoi diagram and export it to Comsol Multiphysics as a 2D geometry through LiveLink for MATLAB. Unfortunately, there is no built in option for higher order diagrams. This is part of my PhD research project. voronoin n-D Voronoi diagram Syntax [V,C] = voronoin(X) Description [V,C] = voronoin(X) returns Voronoi vertices V and the Voronoi cells C of the Voronoi diagram of X. For each input point, the surrounding region contains all points on the plane that are closest to it compared to the other input points. See Triangulation Matrix Format for further details on this data structure. So, I want to see which region of the Voronoi diagram the point (x, y, z) falls in. To fill the cells with color, use voronoin with n = 2 to get the indices of each cell, and then use patch and other plot functions to generate the figure.
