Each call to xlswrite() launches Excel, opens the workbook, transfers the data, saves the workbook, and shuts down Excel. You'd be launching Excel 110 times, and shutting down Excel 110 times. This will take a very long time. You should learn how to make up an array to call xlswrite() just one time AFTER the loop.
Or else use ActiveX (if you're using Windows) so that you just open Excel once and shutdown Excel once, with 110 pokes of data (which will be instantaneous). I've attached a demo of using ActiveX to control Excel.
