Since you have a timetable you can use the isweekend function to get true and false values (which you could convert to categorical or leave as logical) from the RowTimes property.
% Make some sample data
T = datetime('today');
thisWeek = T + days(0:6);
% Process each day
for whichDay = 1:numel(thisWeek)
D = thisWeek(whichDay);
if isweekend(D)
fprintf("%s is not a weekday.\n", D)
else
fprintf("%s is a weekday.\n", D);
end
end
If you wanted to get a categorical array, consider calling categorical on the output of day with the 'dayofweek' input.
