For Maple 2016 and later - use LocalVolatility.maple, a Maple Workbook that includes both worksheet and data.

For Maple 2015 and earlier, we have included an earlier version of this application. It performs the same calculations and creates the same plots, but does not take advantage of newer data handling and visualization tools. Use "Local Volatility pre2016.mw", and make sure that "SP500.xls" is in the same folder.
