Path: Orbit/OrbitCoord
% Computes relative coordinates between two orbits.
Find relative coordinates between an orbit defined by r and v
and orbit with position vector r2. This coordinate system uses Kaplan's
convention and is consistent with LinOrb.
--------------------------------------------------------------------------
Form:
d = RelativeCoord( r, v, r2, v2 )
--------------------------------------------------------------------------
------
Inputs
------
r (3,:) Position vector
v (3,:) Velocity vector
r2 (3,:) Second orbit position
v2 (3,:) Second orbit velocity
-------
Outputs
-------
d (3,:) Relative position [dr;rtheta;z]
(6,:) And velocity if v2 is entered
