Add n days to juliandate
1 view (last 30 days)
Asatur Khurshudyan on 23 Jan 2020
I am using
planetEphemeris(juliandate(y, m, d), 'Sun', 'Mars')
to extract the position of Mars relative to Sun at a given date
y, m, d.
Now, I need to add a specific number of days to that date and extract the position of the new date. Apparently,
planetEphemeris(juliandate(y, m, d) + n, 'Sun', 'Mars')
does not work. What do I need to add instead of n to have the position of Mars in, say, 100 days after that date?
Thank you in advance.

It seems to work just fine as far as I can see. When I compare:
jd0 = juliandate(2020, 2, 14);
jd0p100 =juliandate(2020, 2, 14) + 100;
jd0p101 =juliandate(2020, 2, 14 + 100);
isequal(jd0p100,jd0p101) % returns true
jd0p101 - jd0 % returns 100
everything seems OK.
What is your problem? What matlab-version are you using?
