title: Array inside array in MATLAB
body: <p>If <code>n=4</code> for example, How to create an array like this in MATLAB?</p>
  
  <pre><code>[[0] [0 0] [0 0 0] [0 0 0 0]]
  </code></pre>
  
  <p>Is there a way to create an array inside a <code>for</code> loop, for example ?
  This is what I want to achieve (I know it's wrong code):</p>
  
  <pre><code>for i=1:n
     table(i)=zeros(i);
  end
  </code></pre>
