clear All Close All clc rand('state',0); xx=rand(1,5)*5; yy=rand(1,5)*5; R=3; nodearray=[xx;yy]'; for i=1:5 hold on % x=nodearray(n,1); %y=nodearray(n,2); plot(xx,yy,'*'); text(xx(i),yy(i),num2str(i)); hold on title('Speed'); for j=1:5 d=sqrt((xx(i)-xx(j))^2+(yy(i)-yy(j))^2); if d<=R

    line([xx(i) xx(j)],[yy(i) yy(j)])
     end 
     end    
    axis([0 6 0 6])
end
