(* G&R 2004 status: done.  Added sliced versions. *)

(* TODO: This stores the vectors as vectors of pointers to cells
   containing the real values.  It would be more efficient to store
   numbers directly in a byte-vector.  We could use the move_bytes
   function to load and store reals although it would probably be
   better to define RTS functions to load and store reals. *)
