title: Is it possible to make a matrix with rows that have different #rows on Matlab?
body: <p>I want to make a matrix, or another kind of variable that as rows. The thing is that with the first row there can be 10 numbers(columns), and the second only 3, and the third 5, and so on...
  Is that possible? And how?</p>
  
  <p>EDIT: I need to through a matrix, then store the numbers. It's a m-by-2 matrix. I'm going through it with a for loop. Like so:</p>
  
  <pre><code>rows = size (mtx, 1);
  for i = 1 : rows
      var = m (i, :);
      if m(2) is in A{something}
          if m(3) is in A{something}
              continue (ignore)
          else
              store m(3) in A{something}
          end
      else
          if m(3) is in A{something}
              store m(2) in A{something}
          else store both m(2) and m(3) in A{Newsomething}
          end
      end
  end
  </code></pre>
