For further -- documentation, see http://haskell.org/cabal/users-guide/ name: free-vector-spaces version: 0.1.5.0 synopsis: Instantiate the classes from the vector-space package with types from linear description: The package offers efficient vector types — where vector means /element of a free vector space/, i.e. fixed-length arrays of numbers. The entire interface of that library is based on this concept of free vectors with a canonical coordinate representation. . While this is practically speaking often useful, it is also . * Questionable in terms of conceptual elegance. The idea of a vector has originally not much to do with number-arrays; in physics a vector is just a quantity with /magnitude and direction/. Only by fixing a basis can a coordinate representation arise from that. . * Not as safe as we'd like. The typical linear-algebra languages like Matlab or Fortran are notorious for hard-to spot mistakes that often arise from the total reliance on coordinate representations (every vector/linear map is just a matrix of number). @linear@ already avoids most of these problems because it can at least check dimensions at compile-time and usually doesn't need any indices, but some trouble still remains. E.g., two different 3-dimensional spaces are indistinguishable by the type system (unless you wrap one of them in a @newtype@, however that also needs to be parameterised on the coordinate type to work with the rest of the library). . The library has arguably a better (albeit less complete) interface. To gain access to that interface with the more efficient types from @linear@, we here provide the necessary orphan instances. homepage: https://github.com/leftaroundabout/free-vector-spaces license: BSD3 license-file: LICENSE author: Justus Sagemüller maintainer: (@) sagemueller $ geo.uni-koeln.de -- copyright: category: Math build-type: Simple -- extra-source-files: cabal-version: >=1.10 source-repository head type: git location: git://github.com/leftaroundabout/free-vector-spaces.git library exposed-modules: Data.VectorSpace.Free , Data.VectorSpace.Free.FiniteSupportedSequence , Data.VectorSpace.Free.Sequence other-modules: Data.VectorSpace.Free.Class -- other-extensions: build-depends: base >=4.6 && <5.1, vector-space >=0.11 && <0.13, MemoTrie, linear >=1.18 && <1.23, lens >= 4 && < 5, vector, pragmatic-show >=0.1.2 && <0.2 ghc-options: -O2 -- hs-source-dirs: default-language: Haskell2010
