Ran in:
I am not exactly certain what the desired result is, however the retime funciton will likely produce it, regardless.
Assuming that is to re-sample the table from 0.1 second resolution to 0.5 second resolution,
T1 = readtable('https://www.mathworks.com/matlabcentral/answers/uploaded_files/797754/Book2.xlsx', 'VariableNamingRule','preserve')
T1 = 11×2 table
time data2 ______ _______ 9334 0.48445 9334.1 0.48506 9334.2 0.48386 9334.3 0.48294 9334.4 0.48416 9334.5 0.48688 9334.6 0.48765 9334.7 0.49532 9334.8 0.5 9334.9 0.50005 9335 0.5001
T1.time = seconds(T1.time); % Convert 'time' From Numeric To A 'duration' Array
TT1 = table2timetable(T1)
TT1 = 11×1 timetable
time data2 __________ _______ 9334 sec 0.48445 9334.1 sec 0.48506 9334.2 sec 0.48386 9334.3 sec 0.48294 9334.4 sec 0.48416 9334.5 sec 0.48688 9334.6 sec 0.48765 9334.7 sec 0.49532 9334.8 sec 0.5 9334.9 sec 0.50005 9335 sec 0.5001
TT1 = retime(TT1, 'regular','linear', 'Timestep',seconds(0.5))
TT1 = 3×1 timetable
time data2 __________ _______ 9334 sec 0.48445 9334.5 sec 0.48688 9335 sec 0.5001
The interpolation method is required in the event that there are missing times. It does not affect values that already exist at the chosen times.
