% Computes a gravity gradient torque from r and mu.
q transforms from the frame in which r is defined to the body frame.
Since version 10.
--------------------------------------------------------------------------
Form:
t = GravityGradientFromR( q, inr, r, mu )
--------------------------------------------------------------------------
------
Inputs
------
q (4,1) Quaternion from the r frame to Body
inr (3,3) Inertia matrix
r (3,:) Orbit from the earth to the spacecraft
in the spacecraft body frame (the same frame as
the inertia matrix.)
mu (1,1) Gravitational Parameter
-------
Outputs
-------
t (3,:) Torque (units will be consistent with inertia)
