            [1,1] = size(target); cell = class(target)

   the call:

      [pos, lt] = <b>cspice_spkpos</b>(targ, et, ref, abcorr, obs)

   returns:

      pos   the Cartesian position vector(s) representing the
            position of the target body relative
            to the specified observer. 'pos' is corrected for
            the specified aberrations, and is expressed with
            respect to the reference frame specified by 'ref'.

            [3,n] = size(pos); double = class(pos)
