Abstract
dd_functions
which provides symbolic features to work with DD-finite functions, a natural extension of the class of holonomic or D-finite functions, on the computer. Closure properties, composition of DD-finite functions and sequence extraction are key features of this package. All these operations reduce the problem to linear algebra computations where classical division-free algorithms are used.
