title: Load all data files in a directory in Octave
body: <p>I need to load all data in a directory into octave (no matter what their filenames are), so that the data from separate files are loaded into separate matrices. How can I do that?</p>
  
  <p>I've tried to use <code>dir</code> and <code>glob</code> and then use a <code>for</code> loop but I don't know how to get matrices from cells.</p>
