function dms=rad2dms(rad)
% RAD2DMS  Converts radians to degrees-minutes-seconds. Vectorized.
% Version: 12 Mar 00
% Useage:  dms=rad2dms(rad)
% Input:   rad - vector of angles in radians
% Output:  dms - [d m s] array of angles in deg-min-sec, where
%                d = vector of degrees
%                m = vector of minutes
%                s = vector of seconds
