function rad=dms2rad(dms)
% DMS2RAD  Converts degrees-minutes-seconds to radians.
%   Vectorized.
% Version: 12 Mar 00
% Useage:  rad=dms2rad(dms)
% Input:   dms - [d m s] array of angles in deg-min-sec, where
%                d = vector of degrees
%                m = vector of minutes
%                s = vector of seconds
% Output: rad - vector of angles in radians
