It appears the question has been edited so that the links are now to a .png file, a .mat file, and a small .txt file that show the command that was used.

Maybe this will help:

clc;close;clear
contour(peaks)
hold on
[c,h] = contour(peaks,[5,5]);
c(:,1)=[]; % extract coordinates
plot(c(1,:),c(2,:),'k--','linewidth',2)

No what? Would you like us to be as brief as you are to us? How would you like us to answer you in one word responses? Would that help you? OK, so here's my word: "huh?"
