Math::Series defines a class for simple mathematic series with a recursive
|
|
definition such as x_(n+1) = 1 / (x_n + 1). Such a recursive definition is
|
|
treated as a sequence whose elements will be added to form a series. You
|
|
can refer to the previous sequence element as well as to the current index
|
|
in the series. Creation of a Math::Series object is described below in the
|
|
paragraph about the constructor.
|
|
|
|
Math::Series 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::Series uses Math::Symbolic for its implementation, all
|
|
results will be Math::Symbolic objects which may contain other variables
|
|
than the sequence variable and the iterator variable.
|
|
|
|
Each Math::Series object is an iterator to iterate over the elements of
|
|
the series 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.
