title: How can I drop one element from a cell array?
body: <p>I have some 1D cell arrays that look like this:</p>
  
  <pre><code>foo={'', 'some', 'important', '', 'data'}
  </code></pre>
  
  <p>I want to get rid of the empty strings that are scattered throughout the cell arrays, making something like this:</p>
  
  <pre><code>{'some', 'important', 'data'}
  </code></pre>
  
  <p>I know how to find the empty strings, but all of the documentation that I've been able to find regarding dropping elements from cell arrays leaves a something in the position being dropped. <strong>How can I remove an element from a cell array, and have the resulting array shrink so as to only contain the relevant data?</strong></p>
