The rtable_elems(A) function, where A is an Array, Matrix, or Vector, returns a set of equations of the form (indices)=value specifying the values of the elements in rtable A.

Only the elements that explicitly need to be specified, taking into account storage, are returned.

For Arrays, this function is equivalent to op(3, A). For Matrices and Vectors, this is equivalent to op(2, A).

The rtable_num_elems(A) function, where A is an Array, Matrix, or Vector, returns the number of elements actually stored in rtable A.

This rtable_num_elems(A, opt) function performs in the same manner, except that one of the following options may be specified.

The rtable_num_elems command is thread-safe as of Maple 15.
