I am trying to create a single figure in which I plot the vectors whose x, y points come from a matrix
V = [ 0 2.0840 -8.6160 -0.5878 2.3511; 12.0000 2.1580 21.3252 -0.8090 3.2361]
in such a manner that the beginning of the second vector is at the end of the first, etc. and the resultant force vector is made clear.
thank you in advance if you are able to help me.

Brennan,
Have you tried using quiver?
V = [0 2.0840 -8.6160 -0.5878 2.3511; 12.0000 2.1580 21.3252 -0.8090 3.2361]';
startPoints = cumsum(V);
startPoints = [0 0; startPoints(1:end-1,:)];
quiver(startPoints(:,1),startPoints(:,2),V(:,1),V(:,2),0);
The last argument to quiver (scale = 0) turns off auto-scaling of the vector lengths.
Hope this helps.
