This struct corresponds directly to the options availableto the rtable constructor in Maple. 3RtableAppendAttribute appends the name attribute to the list ofattributes in the RtableSettings structure.RtableAppendIndFn appends the indexing function, infn to the listof indexing functions in the RtableSettings structure. Note that infnmust be a valid Maple name or table-reference. For example,RTableAppendIndFn(kv,&settings,ToMapleName(kv,"symmetric",TRUE));RTableAppendIndFn(kv,&settings,EvalMapleStatement(kv,"triangular[upper]"));3 For more information, see ?rtable.
