Generating a range of datetime data is a common data analysis and simulation task. Here we show examples of generating datetime vectors for:

• datetime
• datenum

datetime

Matlab “datetime” is strongly encouraged over legacy datenum(). datetime has a native ability to generate range of datetime like:

function times = datetime_range(tstart, tend, ts)
arguments
  tstart (1,1) datetime
  tend (1,1) datetime
  ts (1,1) duration
end

dt = tstart:ts:tend

end

GNU Octave datetime

GNU Octave can use many datetime features via the Octave-Tablicious package.

then load by:

pkg load tablicious

datenum

Generate a range of datenum times like:

function times = datetime_range(tstart, tend, ts)
% ts: seconds

times = tstart:ts/86400:tend;

end
