Creation of a +Math::Sequence object is described below in the paragraph about the +constructor. + +Math::Sequence uses Math::Symbolic to parse and modify the recursive +sequence definitions. That means you specify the sequence as a string +which is parsed by Math::Symbolic. Alternatively, you can pass the +constructor a Math::Symbolic tree directly. + +Because Math::Sequence uses Math::Symbolic for its implementation, all +results will be Math::Symbolic objects which may contain other variables +than the sequence variable itself. + +Each Math::Sequence object is an iterator to iterate over the elements of +the sequence starting at the first element (which was specified by the +starting element, the second argument to the new() constructor). It offers +facilities to cache all calculated elements and access any element +directly, though unless the element has been cached in a previous +calculation, this is just a shortcut for repeated use of the iterator. + +Every element in the sequence may only access its predecessor, not the +elements before that. + +WWW: http://search.cpan.org/dist/Math-Sequence +Author: Steffen Mueller <sequence-module@steffen-mueller.net> |
