title: white space in cell array
body: <p>I am using textscan to read text file and I get &lt;55x1 cell> 
  examples:</p>
  
  <pre><code> 'aa a aa'
   'a  aaaa a'
   'a =  aaaaa'
   'aaaaaa'
   ' a a a aaa'
   'aa'
   'aaa'
   'aaaa'
    .
    . 
    .
    .
  </code></pre>
  
  <p>I want to delete the white spaces in each sting
  If I have a sting </p>
  
  <pre><code> string = 'I am 24 Years    old'
  </code></pre>
  
  <p>And I use </p>
  
  <pre><code>  string(ismember(string,' ')) = [];
  </code></pre>
  
  <p>it will eliminate the spaces and I will get </p>
  
  <pre><code> 'Iam24Yearsold'
  </code></pre>
  
  <p>But with the cell doesn't work or I don't know how to do it
  How can I do that? any suggestions please?</p>
