Writing output to different columns of a file
<p>Hi I was wondering if there is any function library that lets me do this conveniently or if you have any suggestions as to how I might do this elegantly without writing lines and lines of code (which is what I ended up doing with ofstream).</p>

<pre><code>Loop over i
   Loop over j
      Evaluate f(i*alpha,j);
      Write f to column i;
</code></pre>

<p>Something like this. I need to compare a hundred different eigenfunction of a QM problem and I rather not write a file per value of alpha, will make plotting easier as well.</p>

<p>I did google without any usuable results, appreciate any help :)</p>
