title: Setup arrays from tabular data in txt file with MATLAB
body: <p>So basically, I have data in a text file like so:</p>
  
  <pre><code>100 5 10 20 someval someval
  200 6 20 12 someval someval
  300 7 30 13 someval someval
  </code></pre>
  
  <p>The first 3 tokens would by used as (x, y, z) coordinates, while the fourth number will be used to create a color to use the surf(x,y,x,c) function. I like to be able to store the other values in the line too.</p>
