15.5.272 gc2gde

gc2gde(xyz, a, f)

[SOFA] Returns geodetic coordinates (eastward longitude in radians, northward latitude in radians, height above the ellipsoid in meters) corresponding to geocentric coordinates xyz using a reference ellipsoid with equatorial radius a and flattening f. xyz and a must be in the same units, and the returned height is given in that same unit, too. xyz must have 3 elements in its first dimension. a and f must each have a single element. The result has the same dimensions as xyz.
