return the elements of an rtable
return the number of elements in an rtable
(optional) name; element status
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.
size of the rtable as specified by its bounds
number of entries actually stored (default)
number of nonzero elements of the rtable
number of stored nonzero elements of the rtable
number of bytes of storage allocated for data in the rtable
number of elements for which storage has been allocated
The rtable_num_elems command is thread-safe as of Maple 15.
For more information on thread safety, see index/threadsafe.
