In your case

M=[1,2;3,4;4,1;2,3]
g = graph(M(:, 1), M(:, 2));
h = plot(g, 'NodeLabe', {});
t = text(h.XData,h.YData,{'1','2','3','4'},'FontSize',14);

Thank you. if I have a 100 node, how can I use this code?

t = text(h.XData,h.YData,{'1','2','3','4'},'FontSize',14);

% change 4 to 100 for 100 nodes
t = text(h.XData,h.YData,strsplit(num2str(1:4)),'FontSize',14);
