vector-space is library that provides 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 0.4 contains some modules that require ghc 6.10 or better. For instance, Data.AVectorSpace is a 6.10-friendly replacement for Data.VectorSpace. After a while, when 6.10 is widespread, I'll switch over entirely and eliminate the earlier versions.

Besides this wiki page, here are more ways to find out about vector-space:
