This module defines auxiliary computations such as interpolation ones that complement the memoization, for example. There are scan computations too.

- initTransform :: Transform a a
- discreteTransform :: Transform a a
- interpolatingTransform :: Transform a a
- scanTransform :: (a -> b -> a) -> a -> Transform a a -> Transform b a
- scan1Transform :: (a -> a -> a) -> Transform a a -> Transform a a

# Interpolation

initTransform :: Transform a a Source

A transform that returns the initial value.

discreteTransform :: Transform a a Source

A transform that discretizes the computation in the integration time points.

interpolatingTransform :: Transform a a Source

A tranform that interpolates the computation based on the integration time points only.
Unlike the `discreteTransform`

computation it knows about the intermediate
time points that are used in the Runge-Kutta method.

# Scans

scanTransform :: (a -> b -> a) -> a -> Transform a a -> Transform b a Source

Like the standard `scanl`

function but applied to values in
the integration time points. The accumulator values are transformed
according to the third argument, which should be either
`memo0Transform`

or its unboxed version.

scan1Transform :: (a -> a -> a) -> Transform a a -> Transform a a Source

Like the standard `scanl1`

function but applied to values in
the integration time points. The accumulator values are transformed
according to the second argument, which should be either
`memo0Transform`

or its unboxed version.
