Type-level \"branding\" is used to both prevent the end user from confusing infinitesimals and to limit unsafe access to the implementation details of each Mode. . Each mode has a separate module full of combinators. . * @Numeric.AD.Mode.Forward@ provides basic forward-mode AD. It is good for computing simple derivatives. . * @Numeric.AD.Mode.Reverse@ uses benign side-effects to compute reverse-mode AD. It is good for computing gradients in one pass. It generates a Wengert list (linear tape) using @Data.Reflection@. . * @Numeric.AD.Mode.Kahn@ uses benign side-effects to compute reverse-mode AD. It is good for computing gradients in one pass. It generates a tree-like tape that needs to be topologically sorted in the end. . * @Numeric.AD.Mode.Sparse@ computes a sparse forward-mode AD tower. It is good for higher derivatives or large numbers of outputs. . * @Numeric.AD.Mode.Tower@ computes a dense forward-mode AD tower useful for higher derivatives of single input functions. . * @Numeric.AD@ computes using whichever mode or combination thereof is suitable to each individual combinator. . While not every mode can provide all operations, the following basic operations are supported, modified as appropriate by the suffixes below: . * 'grad' computes the gradient (partial derivatives) of a function at a point. . * 'jacobian' computes the Jacobian matrix of a function at a point. . * 'diff' computes the derivative of a function at a point. . * 'du' computes a directional derivative of a function at a point. . * 'hessian' computes the Hessian matrix (matrix of second partial derivatives) of a function at a point. . The following suffixes alter the meanings of the functions above as follows: . * @\'@ -- also return the answer . * @With@ lets the user supply a function to blend the input with the output . * @F@ is a version of the base function lifted to return a 'Traversable' (or 'Functor') result . * @s@ means the function returns all higher derivatives in a list or f-branching 'Stream' . * @T@ means the result is transposed with respect to the traditional formulation. . * @0@ means that the resulting derivative list is padded with 0s at the end. source-repository head type: git location: git://github.com/ekmett/ad.git library extensions: CPP hs-source-dirs: src other-extensions: BangPatterns DeriveDataTypeable FlexibleContexts FlexibleInstances FunctionalDependencies GeneralizedNewtypeDeriving MultiParamTypeClasses PatternGuards Rank2Types ScopedTypeVariables TemplateHaskell TypeFamilies TypeOperators UndecidableInstances build-depends: array >= 0.2 && < 0.5, base >= 4.5 && < 5, comonad == 3.0.*, containers >= 0.2 && < 0.6, data-reify >= 0.6 && < 0.7, free >= 3.0 && <= 3.4, mtl, reflection >= 1.1.6 && < 1.2, tagged >= 0.4.2.1 && < 0.5, template-haskell >= 2.5 && < 2.9 exposed-modules: Numeric.AD Numeric.AD.Types Numeric.AD.Newton Numeric.AD.Halley Numeric.AD.Mode.Directed Numeric.AD.Mode.Forward Numeric.AD.Mode.Kahn Numeric.AD.Mode.Reverse Numeric.AD.Mode.Tower Numeric.AD.Mode.Sparse Numeric.AD.Variadic Numeric.AD.Variadic.Kahn Numeric.AD.Variadic.Sparse Numeric.AD.Internal.Classes Numeric.AD.Internal.Combinators Numeric.AD.Internal.Forward Numeric.AD.Internal.Tower Numeric.AD.Internal.Kahn Numeric.AD.Internal.Reverse Numeric.AD.Internal.Var Numeric.AD.Internal.Sparse Numeric.AD.Internal.Dense Numeric.AD.Internal.Composition other-modules: Numeric.AD.Internal.Types Numeric.AD.Internal.Jet Numeric.AD.Internal.Identity ghc-options: -Wall -fspec-constr -fdicts-cheap -O2 -- Verify the results of the examples test-suite doctests type: exitcode-stdio-1.0 main-is: doctests.hs build-depends: base, directory, doctest >= 0.9.0.1 && <= 0.10, filepath, mtl ghc-options: -Wall -threaded if impl(ghc<7.6) ghc-options: -Werror hs-source-dirs: tests
