Hi,
I have the follwoing points:
%define points
ri = [0.3 0.1 ;
0.7 0.1 ;
0.5 0.3 ;
0.1 0.3 ;
0.1 0.7 ;
0.3 0.5 ;
0.5 0.7 ;
0.3 0.9 ;
0.7 0.9 ;
0.9 0.3 ;
0.9 0.7 ;
0.7 0.5];
%visualise points
plot(ri(:,1),ri(:,2),'rx','LineWidth', 1,'MarkerSize', 12)
xlabel('$r_x$','interpreter','latex')
ylabel('$r_y$','interpreter','latex')
xlim([0 1])
ylim([0 1])
set(gca,'TickLabelInterpreter','latex','FontSize',11)
axis square
grid on
The result of the previous plotting will be as shown on the left. However, I would like to add the number of the point right next to it on the plot based on its order in the vector, as shown on the right.
Any help would be appreciated.

you could add the line
text(ri(:,1),ri(:,2)+0.05,cellstr(num2str((1:size(ri,1))')))
or
text(ri(:,1),ri(:,2)+0.05,strsplit(num2str(1:size(ri,1))))
