It could be automated, something like:
xdata = [2 2 0 2 5;
2 8 2 4 5;
8 8 2 4 8];
ydata = [4 4 4 2 0;
8 4 6 2 2;
4 0 4 0 0];
zdata = zeros(3,5);
patch(xdata,ydata,zdata,'w')
mnx = sum(xdata)./size(xdata,1); % Or MEAN...
mny = sum(ydata)./size(ydata,1);
for ii = 1:numel(mnx)
T(ii) = text(mnx(ii),mny(ii),num2str(ii));
end
set(T,'color','b','fonts',12,'fontweight','bold')
The code after the patch creation could be put into a function M-file which takes the patch object's handle as an arg. Then from there extracts the vertices and does it's job. Of course it should go without saying that this approach will not work for certain patch shapes...
