15.5.276 gd2gce

gd2gce(eph, a, f)

[SOFA] Returns geocentric coordinates (x, y, z) corresponding to geodetic coordinates eph (east longitude in radians, north latitude in radians, height) for the reference ellipsoid with equatorial radius a and flattening f. a, the height, and the returned coordinates x, y, z are all in the same units. eph must have 3 elements in its first dimension. a and f must have exactly one element. The result has the same dimensions as eph.
