The rtable_dims(A) function, where A is an Array, Matrix, or Vector, returns a sequence of integer ranges representing the bounds of each dimension of rtable A.

For a 0-dimensional rtable, NULL is returned. In the case that A is an Array, this is equivalent to op(2, A).

For Matrices and Vectors, this function is similar to LinearAlgebra[Dimension].

The rtable_num_dims(A) function, where A is an Array, Matrix, or Vector, returns the number of dimensions of rtable A.

This is equivalent to nops([rtable_dims(A)]).

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