# rotationEqjEcl
|
|
|
|
fun [rotationEqjEcl](rotation-eqj-ecl.md)(): [RotationMatrix](-rotation-matrix/index.md)
|
|
|
|
Calculates a rotation matrix from J2000 mean equator (EQJ) to J2000 mean ecliptic (ECL).
|
|
|
|
This is one of the family of functions that returns a rotation matrix for converting from one orientation to another. Source: EQJ = equatorial system, using equator at J2000 epoch. Target: ECL = ecliptic system, using equator at J2000 epoch.
