Hi,
I would like to write a script that scrolls through my five minutes resolved timetable / table to select identifies all the days that are Mondays and then group them based on the datetime variable of the table/timetable.
I have tried several other ways to do it including the one below. Instead, if I specify the the day as 1, it returns all the first days of the periods (in this case months) and not specifically the Mondays.
Day1=HHB1(1==day(HHB1.VarName1),:); % HHB1 is the datetime object
%%
Any help?

By default DAY returns the day of the month, so you need to specify its second argument like this:
d = day(t,'dayofweek')
