title: Angle between two vectors matlab
body: <p>I want to calculate the angle between 2 vectors <code>V = [Vx Vy Vz]</code> and <code>B = [Bx By Bz]</code>.
   is this formula correct?</p>
  
  <pre><code>VdotB = (Vx*Bx + Vy*By + Vz*Bz)
  
   Angle = acosd (VdotB / norm(V)*norm(B))
  </code></pre>
  
  <p>and is there any other way to calculate it?</p>
  
  <p>My question is not for normalizing the vectors or make it easier. I am asking about how to get the angle between this two vectors</p>
