title: Octave appending in a 2D cell array
body: <p>I'm trying to append an element at the end of a 2D cell array row. My code is:</p>
  
  <pre><code>b = cell(5, 0)
  b(1) = {b(1, :), 2}   % Trying to append at the end of the first row
  </code></pre>
  
  <p>This gives me the error: <code>error: A(I) = X: X must have the same size as I</code></p>
  
  <p>I've also tried various other forms, such as: </p>
  
  <pre><code>b = cell(5, 0)
  b(1, end+1) = 2   % Ok, inserts 2 at [1,1]
  b(2, end+1) = 3   % No, inserts 3 at [2,2] instead of [2, 1]
  </code></pre>
