title: MATLAB does not read multiple worksheets in basic mode
body: <p>I am trying to read an xlsx sheet in basic mode on a windows 10 machine without excel installed. I believe I am supposed to use the 'basic' flag to make this happen (MATLAB will default to it anyways). I read the sheets in the excel file using xlsfinfo command and tried to use that to read the 8th sheet, </p>
  
  <pre><code>[status,sheets,format] = xlsfinfo(filename)
  xlsread(filename,sheets{8},'','basic');
  </code></pre>
  
  <p>but it always gives me an error</p>
  
  <pre><code>Error using xlsread (line 247)
  Worksheet &lt;8th worksheet name&gt; not found.
  </code></pre>
  
  <p>I can read this worksheet in the non basic mode on a computer with excel installed. What may be the problem?</p>
