VAtm:

Path: Orbit/OrbitMechanics

% Atmospheric velocity from position and planetary rate.

   This routine assumes the Earth rotates perfectly around its z axis. For
   a higher fidelity result you must compute the Earth-fixed tranformation
   for a particular date.

   Has a built-in demo.

   Since version 1.

   Form:
   [v, vMag] = VAtm( r, wP )

   ------
   Inputs
   ------
   r          (3,:)     r in the ECI frame
   wP         (1,1)     Planetary rotation rate (rad/sec), default is Earth

   -------
   Outputs
   -------
   v          (3,:)     v in the ECI frame
   vMag       (1,:)     Magnitude
