MATLAB: How to calculate series of values by specifying starting time using datenum???????

serialdatenumbertime

Hello,

kindly help to solve this issue

I just to want to find the serialdatenumber by specifying the start time and end time using datenum!!!!

%%%%%my code%%%%
starttime = datenum(2018,03,23,10,00,00)
endtime = datenum(2018,03,23,10,10,00)
tme = starttime:endtime

I just need to know how to calculate serialdatenumber for minutes,seconds,milliseconds from 10:00:00 to 10:10:00

starttime = datenum(2018,03,23,10,00,00)
endtime = datenum(2018,03,23,10,10,00)
ms = 1/(24*60*60*1000);
tme = starttime:ms:endtime;

This will be 60001 elements long.

elseif factoridx == 5   %100000
  ms = 36525;              %approximate century resolution
elseif factoridx < 0
  error('time scales smaller than millisecond do not exist for serial date numbers');
else
  error('time scales larger than century are unreliable for serial date numbers');
end
starttime = datenum(2018,03,23,10,00,00)
endtime = datenum(2018,03,23,10,10,00)
tme = starttime:ms:endtime;

';Start_time, 2007-02-01, 00:48:23.729'
';Start_time, 2007-03-01, 00:48:23.729'

';Start_time, 2007-05-01, 00:48:23.729'
';Start_time, 2007-06-01, 00:48:23.729'}; 
% Remove stuff at beginning
d = strrep(d, ';Start_time, ', ''); 
% convert to datetime (use 'Format' property to specify format of output)
dates = datetime(d,'InputFormat','yyyy-MM-dd, hh:mm:ss.S');

% RESULT:
  6×1 datetime array
