Bindings.LevMar.CurryFriendly

Curry friendly variants of the Levenberg-Marquardt algorithms in Bindings.LevMar.

(This module re-exports all the necessary types and function from Bindings.LevMar, so there's no need to import that module when you want to use this one.)

Model & Jacobian

type Model r = Ptr r -> Ptr r -> CInt -> CInt -> Ptr () -> IO ()

Functional relation describing measurements.

type Jacobian a = Model a

withModel :: Model a -> (FunPtr (Model a) -> IO b) -> IO b

withJacobian :: Jacobian a -> (FunPtr (Jacobian a) -> IO b) -> IO b

Handy type synonyms used in the curry friendly types.

type BoxConstraints cr a = Ptr cr -> Ptr cr -> a

type LinearConstraints cr a = Ptr cr -> Ptr cr -> CInt -> a

type Weights cr a = Ptr cr -> a

Curry friendly types of the Levenberg-Marquardt algorithms.

type LevMarDif cr = LevMarDif cr

type LevMarBCDer cr = BoxConstraints cr (LevMarDer cr)

type LevMarBCDif cr = BoxConstraints cr (LevMarDif cr)

type LevMarLecDer cr = LinearConstraints cr (LevMarDer cr)

type LevMarLecDif cr = LinearConstraints cr (LevMarDif cr)

type LevMarBLecDer cr = BoxConstraints cr (LinearConstraints cr (Weights cr (LevMarDer cr)))

type LevMarBLecDif cr = BoxConstraints cr (LinearConstraints cr (Weights cr (LevMarDif cr)))
