title: Add a vector to all columns of a matrix with ArrayFire
body: <p>What is the best way to add a vector to all columns of a Matrix with ArrayFire?</p>
  
  <p>At the moment i'm using a <code>gfor</code> loop, but that seems wrong for such a simple task.</p>
  
  <pre><code>gfor(af::seq i, M.dims(1)) {
      M(af::span, i) += VECTOR;
  }
  </code></pre>
  
  <p>Is there a better way?</p>
