function [test] = Test(a,b,c,d)
    %UNTITLED2 Summary of this function goes here
    %   Detailed explanation goes here
      a= [8 0 -1 2 4 6 3 10 2.5 -5 7 9 11 13 ];
      b = [2 4 6 -1 -2 0.5 0 3.7 1.8 1 0 4 3 2 ];
      %a=[8 0 -1 2 4 6 3 8]
      %b=[2 4 6 -1 -2 0.5 0 2]
      c = hypot(a,b);
      d = sum(c);
      plot(a,b,'--bs','LineWidth',2 ,'MarkerEdgeColor','b',...
          'MarkerFaceColor','g','MarkerSize',10)
      for i=1:a
          text(a(i)+.5,b(i),['\leftarrow node ',num2str(i)]);
      end
      title(['Total course by the length of ' num2str(d) ]);
  end

I want it to show all my nodes number , but it only get until node 8 , anyone can help?

the index in your loop has no meaning :

for i = 1:a % this create the vector 1 2 ... 8 because 8 is the 1st value of a

just change it to

for i=1:length(a)
