15.5.396 numat

numat(epsa, dpsi, deps)

[SOFA] Returns the matrix of nutation based on the mean obliquity of the date epsa (radians) and the nutation components in longitude dpsi and obliquity deps (in radians), with respect to the equinox and ecliptic of date. The mean obliquity epsa must be consistent with the precession-nutation models from which dpsi and deps were obtained. The three arguments must have the same dimensions. The result has those same dimensions with two extra dimensions equal to 3 prefixed.
