hello I want to plot some vectors heads to tails in matlab.what should I do?I have found the compass command but it plots all of the vectors from the origin.

Did you find another alternative? I am looking for something that could be used in simulink?

I show you two methods. Both have their uses, so I'll let you decide which fits your needs:
% Make a vector from (2,3) to (7,8)
axes('pos',[0 0 1 1]);
axis([0 10 0 10])
H = annotation('arrow',[.2 .7],[.3 .8])
Notice, the annotation position is in terms of normalized figure units, not axes units. So if you don't want your axes to fill the figure, or if you want to not have "nice" limits (0-10), you have to do some math. It is not too hard, you just have to do some tweaking.
Another approach is to use the QUIVER function:
% Make a vector from (2,3) to (7,8)
cla
quiver(2,3,5,5)
axis([0 10 0 10])

Hello @Loginatorist, can you explain me your code please? I read the documentation, but it's difficult to pick up the right information.
I tried to plot the array [x1=3,y1=0]-->[x2=-1,y2=7]. Do to it I wrote the code:
%X=x2-x1=-1-3=-4
%Y=y2-y1=7-0=7
quiver(3,0,-4,7)
but I got the array [x1=3,y1=0]-->[x2=-0.6,y2=6.3]. How come?

Disable the scaling:
quiver(3,0,-4,7, 0)
