I have to select the hourly value of relative air saturation and temperature at 14:05 a clock.
From an datetime array containing the 10 minutes values of all dates i created an daily datetime array using:
dt = table2array(T(:,3 ));
dt = datetime(dt, 'InputFormat', 'dd-mmm-yyyy HH-MM-SS');
dt_daily = dt(1:144:end);
how can i add to each dt_daily 14 hours so that i have an index to extract the respective values from the table?
Thanks a lot for your help!
Best regards,
Arthur

Ran in:
I would use the datetime values you already have in your table T.
load T_matlab.mat
ind = timeofday(T.DateTime) == duration(14,05,0);
dayT = T(ind,["DateTime","H_air___","T_air_C_"])
dayT = 101x3 table
DateTime H_air___ T_air_C_ ____________________ ________ ________ 01-Jun-1994 14:05:00 42.31 24.5 02-Jun-1994 14:05:00 48.54 26.48 03-Jun-1994 14:05:00 50.68 20.18 04-Jun-1994 14:05:00 81.76 11.91 05-Jun-1994 14:05:00 68.11 13.05 06-Jun-1994 14:05:00 60.32 15.06 07-Jun-1994 14:05:00 73.92 19.11 08-Jun-1994 14:05:00 53.23 24.73 09-Jun-1994 14:05:00 52.18 13.98 10-Jun-1994 14:05:00 75.54 13.52 11-Jun-1994 14:05:00 66.84 13.47 12-Jun-1994 14:05:00 59.88 17.12 13-Jun-1994 14:05:00 50.32 20.29 14-Jun-1994 14:05:00 64.19 18.04 15-Jun-1994 14:05:00 60.82 21.16 16-Jun-1994 14:05:00 56.84 20.52
