Hello everybody,
i have a big excel file with several sheets. In each sheet are option prices with dates and Strike prices for different expiration dates. For some dates or Strike prices there are no corresponding option prices and as a result there are some empty fields. This leads to errors, when I try to calculate implied volatilities. Is there any way where Mathematica could ignore these empty fields?
Thanks in advance!
