[edit] Abstract

vector-space is library that provides classes and generic operations for additive groups, vector spaces and affine spaces. There are also vector space bases and a general notion of linear maps (linear transformations). The library also defines a type of infinite towers of generalized derivatives. A generalized derivative is a linear map rather than one of the usual concrete representations (scalars, vectors, matrices, ...).

The representation of linear maps uses MemoTrie.

Warning: Starting with version 0.3, this package depends on type families working fairly well, and requires ghc version at least 6.9. Version 0.5 requires ghc 6.10 or better.
