aivika-5.8: A multi-method simulation library

Simulation.Aivika.Transform

Description

Tested with: GHC 8.0.1

The module defines something which is most close to the notion of analogous circuit as an opposite to the digital one.

Synopsis

The Transform Arrow

newtype Transform a b Source #

It allows representing an analogous circuit as an opposite to the digital one.

This is a transform of one time varying function to another usually specified in the integration time points and then interpolated in other time points with help of one of the memoization functions like memo0Dynamics.

Delaying the Transform

Arguments

 :: Dynamics Double the lag time -> Dynamics a the initial value -> Transform a a the delayed transform

Return a delayed transform by the specified lag time and initial value.

This is actually the delayI function wrapped in the Transform type.

The Time Transform

A transform that returns the current modeling time.

Differential and Difference Equations

Arguments

 :: Dynamics Double the initial value -> Transform Double Double map the derivative to an integral

Return a transform that maps the derivative to an integral by the specified initial value.

This is actually the integ function wrapped in the Transform type.

Arguments

 :: Dynamics Double the initial value -> Transform (Either Double Double) Double map either a new Left value or the Right derivative to an integral

Like integTransform but allows either setting a new Left value of the integral, or updating it by the specified Right derivative.

Arguments

 :: (Num a, Unboxed a) => Dynamics a the initial value -> Transform a a map the difference to a sum

Return a transform that maps the difference to a sum by the specified initial value.

This is actually the diffsum function wrapped in the Transform type.

Arguments

 :: (Num a, Unboxed a) => Dynamics a the initial value -> Transform (Either a a) a map either a new Left value or the Right difference to a sum

Like sumTransform but allows either setting a new Left value of the sum, or updating it by the specified Right difference.
