I am looking for a way to get all the vertices of Voronoi plot, I know i can use this:
[v,c] = voronoin([x(:) y(:)])
This will provide the index of the vertices for each polygon and the positions of each. This will also identify the finite vertices. But what I am looking for is the point positions where there is no vertices, but where the polygon line crosses the defined figure axis. IS this possible?
Thank you.

Where ever the length of c{i} is less it is not closed....Check for each length of c{i} and use nearest neighbor to get the points you wanted. You may use knnsearch for nearest points. Hope this helps.

Thank you, but if you look at the attached figure. The positions i am looking to extract are the ones in green. I can kind get the corners, but i need to know which point belong to each polygon. DO you think there is a way to do this?
