Hello,
My script writes to an xls file. I am packaging this as an app to pass onto others to use. However it occurred to me that it could be possible that they don't have excel. I was wondering if there was a way for matlab to check if you have excel installed before writing/opening an excel file.
Thanks

Look at the code for xlswrite, which does
try
Excel = matlab.io.internal.getExcelInstance;
catch exception %#ok<NASGU>
warning(message('MATLAB:xlswrite:NoCOMServer'));

Just now had the chance to get back to this. Thanks, Walter. Do you happen to know what
matlab.io.internal.getExcelInstance
will output if you do not have the application?

It will error in ActiveX attempt, which is why the try/catch
