MATLAB: How to plot error bar at only one location

errorbarmatrix

Suppose, I have this two data. Here the errorbar is plotted for every v. But I need to put error bat at only one particulat index v(4).
u = 1:10:100;
v = [20 30 45 40 60 65 80 75 95 90];
err = 8*ones(size(v));
errorbar(u,v,err)

Best Answer

just plot first without errorbar and than with errorbar for only the 4th value:
plot(u,v,'b')
hold on
errorbar(u(4),v(4),err(4),'b')
