In order to handle the missing data marked with NaN when creating your table of statistics (related to p4 of the project), you can use function nanmean, nanstd, nanmin, nanmax and nanmedian. Consult with MATLAB help to get more familiarized with these built-in functions. Ideally your table should look like this. The following table is related to S1 in Montreal.
