I have a question about the reptime function. I'm trying to count a redistributed data every 24 hr, from a data set that is taken every minute.

TT2 = retime(TT1, 'daily', 'count');

"retime" starts counting 24 hours from the first row. The question that I have is that my data set in TT1 does not have complete 24 hour data set at the end, so when I use 'count' the number of points in the last data bit is lower than in TT1.

How can I use retime on all the data set from TT1?

How about you help people to help you by attaching TT1 in a .mat file?

retime starts counting 24 hours from 00:00:00 of the day in the 1st row, and the total count is equal to the number of row of the input timetable, as shown below. Please tell us more detail of the problem you are facing (attaching .mat file would be quite helpful!).

% Sample timetable
Time = datetime({'2015-12-18 07:02:12';'2015-12-18 08:00:47';...
  '2015-12-18 09:01:37';'2015-12-18 10:03:10';...
  '2015-12-19 02:59:34'});
Temp = [37.3;41.9;45.7;42.3;39.8];
Pressure = [30.1;29.9;30.03;29.9;29.8];
TT = timetable(Time,Temp,Pressure);
retime(TT,'daily','count')
