title: How can I draw vectors in octave?
body: <p>I want to make a program that adds two vectors and plots them together with their addition. But they have to be position vectors.</p>
  
  <p>I tried creating <code>v1=[0;2]</code> and <code>v2=[1;3]</code> but displaying them with <code>plot</code> results in a number of scattered points.</p>
  
  <p>How can I specify the starting position of the vectors, <em>e.g.</em> make <code>v1</code> and <code>v2</code> start from the origin?</p>
