anamorphism
In category theory, the concept of anamorphism ("ana" from the Greek = upwards; "morphism" from the Greek = form, shape) denotes a morphism from a coalgebra to the final coalgebra for that endofunctor. These objects have been applied to functional programming as ''unfolds''. The categorical dual of the anamorphism is the catamorphism. == Anamorphisms in functional programming ==
In functional programming, an anamorphism is a generalization of the concept of ''unfolds'' on lists. Formally, anamorphisms are generic functions that can corecursively construct a result of a certain type and which is parameterized by functions that determine the next single step of the construction.
