Access the row times. The row times are not in a variable. Instead, the vector of row

times is a property of the timetable. However, you can access the row times with dot

syntax. TT.OutageTime is a 1468-by-1 vector of datetime values. Display the first five

rows of TT.OutageTime.

Subscript on Time Range

To select all timetable rows that fall in a time range, create a subscript as a helper, using

the timerange function. The start and end times you specify do not have to match any of

the row times in the timetable.

Select all rows with outages that occurred between January 2002 and December 2003.

Display the first five rows of TT2.

TR = timerange('2002-01-01','2003-12-31');

TT2 = TT(TR,:);
