title: actx matlab syntax for SaveAs: conflict resolution parameter doesn't seem to work
body: <p>I am working on editing CSV spreadsheet from matlab using ActxServer and then saving it as an xlsx. The problem is that I usually already have a file with the same name saved in the same folder so I need to override it. I'd like to be able to override the old file automatically without being asked every time. I tried using conflict resolution parameter in my SaveAs syntax but it did not work. Is there a way to do it and is there a problem with my syntax? Thanks in advance!</p>
  
  <pre><code>Workbook.SaveAs(excelfilename, 51,NaN,NaN,NaN,NaN,NaN,2)
  </code></pre>
