Path: Interplanetary/Ephemeris
% Computes the JPL position vectors of the planets as a function of time.
If no outputs are given will plot the positions of the input planets.
If no inputs are given it will compute the vectors for the entire
solar system. Comparable to SolarSys. The default XY plane is Earth Mean
Equator and Equinox of Reference Epoch (Earth equatorial). The origin is the
center of the sun. Will create a plot when called without outputs.

Form:
[rx0, ry0, rz0, vx, vy, vz] = SolarSysJPL( id, jD, ecl )
--------------------------------------------------------------------------
------
Inputs
------
id (n,1) Numeric ID of planet(s)
jD (m,1) Julian dates
ecl (1,1) Flag for ecliptic plane instead of equatorial
-------
Outputs
-------
rx0 (n,m) x component, one row per planet (au)
ry0 (n,m) y component, one row per planet (au)
rz0 (n,m) z component, one row per planet (au)
vx (n,m) vx component, one row per planet (km/s)
vy (n,m) vy component, one row per planet (km/s)
vz (n,m) vz component, one row per planet (km/s)
n is the number of planets
