title: How to Add a row vector to a column vector like matrix multiplication
body: <p>I have a nx1  vector and a 1xn vector. I want to add them in a special manner like matrix multiplication in an efficient manner (vectorized):</p>
  
  <p>Example:</p>
  
  <pre class="lang-ml prettyprint-override"><code>A=[1 2 3]'
  
  B=[4 5 6]
  
  A \odd_add B = 
  [1+4 1+5 1+6
   2+4 2+5 2+6
   3+4 3+5 3+6
  ]
  </code></pre>
  
  <p>Regards</p>
