Hi!
Can I match by dates and by country names?
I've matched by dates, but the code capture all countries.
Thanks

Images of text are always really hard to work with. Copying the text directly is much better (just FYI for future posts).

isMatch = dateMatches && ismember(T.Country, {'Austria','Belgium'});
Replace dateMatches with your date-matching code that produces a logical vector of date matches.
Replace T with your table name and list the countries you'd like to match.
isMatch is a logical vector of row-matches.

I thought you had alread done that. In your question, "I've matched by dates, but the code capture all countries.".
If you have a list of dates D and a 2nd list of dates D2, to find the dates in D that are listed in D2,
ismember(dateshift(D,'start','day'), dateshift(D2,'start','day'))
If you're trying to find all dates in D that are within range of date1 to date2,
D >= date1 & D <= date2;
