Path: Orbit/OrbitCoord

% Convert ECI to Sun Earth rotating coordinates about the barycenter.
   The coordinate frame is +x pointing at the Earth along
   the Sun-Earth line. +z normal to the Sun-Earth (ecliptic) plane
   and +y completing the set. 
   Computes the plane by looking at the sun vector at jD(k) and then 1 day 
   later. By default, "SunV1" is used to get the sun vector. If a second
   argument is entered, the JPL ephemerides are used.

   Type ECIToSunEarthRot for a demo.

   Since version 11.
   m = ECIToSunEarthRot( jD, JPL )

   jD             (1,:)      Julian date (days)
   JPL            (1,1)      Optional. Enter this input (any value) to use
                             the JPL ephemerides. Otherwise, SunV1 is used.
   m              {:}        Rotation matrices
