math/p5-Math-Sequence 1.00_1

Math::Sequence defines a class for simple mathematic sequences with a recursive definition such as x_(n+1) = 1 / (x_n + 1). 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.
