Can someone tell me what I am doing wrong with this loop?

Ps keeps looping. I just want to stop at mstlength which is 11.

for l=1:mstlength
ls = mst(l,1);
 for p=1:mstlength
    ps = mst(p,2);
       plot([nodes(ls,2) nodes(ps,2)],[nodes(ls,3) nodes(ps,3)],'k.-')
       hold on
  end
end

Thank you

Do you want 11 runs? Then just use one loop

for l=1:mstlength
  ls = mst(l,1);
  ps = mst(p,2);
  plot...
end

Otherwise there's nothing wrong with your loops, l runs from 1 to 11 and for each l, p runs from 1 to 11:

>> mstlength = 11;
for l=1:mstlength
%ls = mst(l,1);
 for p=1:mstlength
   % ps = mst(p,2);
    disp(sprintf('l = %d, p = %d', l, p))    
    %plot([nodes(ls,2) nodes(ps,2)],[nodes(ls,3) nodes(ps,3)],'k.-')
       %hold on
  end
end
l = 1, p = 1
l = 1, p = 2
l = 1, p = 3
l = 1, p = 4
l = 1, p = 5
l = 1, p = 6
l = 1, p = 7
l = 1, p = 8
% more lines here... 
l = 11, p = 8
l = 11, p = 9
l = 11, p = 10
l = 11, p = 11

Thank for your answer. The first one did work.

for l=1:mstlength,
    text(nodes(l,2),nodes(l,3),[' ' num2str(ids(l))],'Color','b','FontWeight','b')
    ls = mst(l,1);
    ps = mst(l,2)
    plot([nodes(ls,2) nodes(ps,2)],[nodes(ls,3) nodes(ps,3)],'k.-')

           hold on
      end;
