title: Gnuplot - How to compute average from different blocks
body: <p>I have a file with different blocks like the following:</p>
  <pre><code>1 2 6 7
  9 3 4 5
  .......
  3 6 2 9
  
  
  4 7 2 7
  9 5 3 7
  .......
  8 3 5 1
  </code></pre>
  <p>If i run <code>stat 'File'</code> the different blocks are recognized. Now I would like to do an average among all the blocks for each element of the blocks (i.e. in the example the resulting element of the 1st row and 1st column will be <code>avg(1, 4)=2.5</code>).</p>
  <p>Is there any way to do this in gnuplot?</p>
