what i am trying to get is something like give two points x1=(1,2),x2= (3,4) , I am connecting the points x1 and x2, and want to get small arrow to indicate the direction of the connection of these two points.

You can insert small arrow over your line plot by selecting Insert menu and selecting item 'Arrow'. You can then resize it and/or edit other properties to suit your needs.

If I well understood your question you want to represent a vector of position ?


So you want representing the two points and then unite them with an arrow.

Is this that you want?

How you generate your first two points and unite them?


To use that arrow I think you should use the quiver function:

>>help quiver

>>x1=[1,2];x2= [3,4] % definirea celor 2 pcte de coordonate date
>>quiver(x1(1),x1(2),x2(1),x2(2));
