I'm generating an excel spreadsheet using the PEAR extension, Spreadsheet_Excel_Writer. I need to add an array formula to one of the cells, but all the info I've read about them only discusses them as if you're in the Excel program itself: it says you have to type in the formula as normal and then press Ctrl+Shift+Enter to switch it to an array formula.
Is there a way I can do this programmatically?
