Calculates a rotation matrix from J2000 mean ecliptic (ECL) to equatorial of-date (EQD).
This is one of the family of functions that returns a rotation matrix
for converting from one orientation to another.
Source: ECL = ecliptic system, using equator at J2000 epoch.
Target: EQD = equatorial system, using equator of date.
