Convert WGS 84 (CTS, ECEF) Coordinates to ECI (CIS, Epoch J2000.0) Coordinates. This function has been vectorized for speed. The associated error in converting between coordinate frames is on the order of 1.2*10^-11 km when compared to STK ephemeris output.

To run this function type the following command in a MATLAB prompt:

>> [r_ECI v_ECI a_ECI] = ECEFtoECI(JD,r_ECEF,v_ECEF,a_ECEF);

Where
JD is a Julian Date Vector [1 x N]
r_ECEF is the position vector in ECEF coordinates [3 x N]
v_ECEF is the velocity vector in ECEF coordinates [3 x N]
a_ECEF is the acceleration vector in ECEF coordinates [3 x N]

r_ECI is the position vector in ECI coordinates [3 x N]
v_ECI is the velocity vector in ECI coordinates [3 x N]
a_ECI is the acceleration vector in ECI coordinates [3 x N]
