This is the program i have written. How do i highlight (bold) the vertex?
x=[1 1 1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 3 3 4 4 4 4 4 4 4 4 5 5 6 6 7 7 7 8 8 8 8 9 9];
y=[1 3 5 7 8 9 10 2 3 4 6 9 1 2 3 5 7 8 10 1 2 4 5 7 8 9 10 1 2 5 8 2 4 8 1 4 6 8 5 7];
axis([0 10 0 10]);
hold on;
scatter(x, y, [], 'filled');
[vx,vy] = voronoi(x,y)
plot(vx,vy,'red')

you can use scatter to plot/highlight the vertices of the Voronoi diagram by adding the lines of code below at the end of your code.
scatter(vx(1,:),vy(1,:),'black');
scatter(vx(2,:),vy(2,:),'black');

You can find the vertices of voronoi diagram using this:
from = [vx(1,:);vy(1,:)];
to = [vx(2,:);vy(2,:)];
Then using "hold on" command you can plot these points on the top of the previous plot with different color or with different linestyle.
