Numeric.FFT.Vector.Plan

Contents

Synopsis

Transform

A transform which may be applied to vectors of different sizes.

Create a Plan of a specific size for this transform.

Constructors

Create a Plan of a specific size. This function is equivalent to planOfType Estimate.

run :: (Vector v a, Vector v b, Storable a, Storable b) => Transform a b -> v a -> v b Source #

Create and run a Plan for the given transform.

Plans

A Plan can be used to run an fftw algorithm for a specific input/output size.

The (only) valid input size for this plan.

The (only) valid output size for this plan.

execute :: (Vector v a, Vector v b, Storable a, Storable b) => Plan a b -> v a -> v b Source #

Run a plan on the given Vector.

If planInputSize p /= length v, then calling execute p v will throw an exception.

Arguments

:: (PrimBase m, MVector v a, MVector v b, Storable a, Storable b)
=> Plan a b	The plan to run.
-> v (PrimState m) a	The input vector.
-> v (PrimState m) b	The output vector.
-> m ()

Run a plan on the given mutable vectors. The same vector may be used for both input and output.

If planInputSize p /= length vIn or planOutputSize p /= length vOut, then calling unsafeExecuteM p vIn vOut will throw an exception.
