% Right-Hand-Side function for solar system object trajectories
You must initialize the JPL ephemerides before running this function.
PlanetPosJPL( 'initialize', planets );
Planets contains the JPL ephemeris ids from 1 to 11.
The force model must be of the form f = ForceModel( r, v, d )
where d can be any data structure.
f is the force vector in N in the ECI frame.
--------------------------------------------------------------------------
Form:
d = RHSTrajectory; % Get the default data structure
RHSTrajectory( x ); % initialize persistent variables
[xDot, p] = RHSTrajectory( x, t, d ); % Call during simulation
--------------------------------------------------------------------------
