cla
quiver(2,3,5,5,0) % Set scale to zero
axis tight
As I told you in your previous question, you need to do some math and transform from figure coords to axes coords to use the figure annotation arrow like you want. This will involve reading the documentation!
If you had read the documentation for QUIVER, you wouldn't have had to wait 2 days to get it right...

I think you can use 'quiver' command.

Can you elaborate about the error?

for example quiver(2,3,5,5) will plot a vector from (2,3).but it will not end at (7,8).
