accelerate-fft: FFT using the Accelerate library

[ accelerate, bsd3, library, math ] [ Propose Tags ]

Rank-polymorphic discrete Fourier transform (DFT), computed with a fast Fourier transform (FFT) algorithm using the Accelerate library. Note that optimised implementations are available via foreign libraries (enabled by default).

Refer to the main Accelerate package for more information:

Automatic Flags

Use CUFFT-based implementation in the LLVM.PTX backend


Use FFTW-based implementation in the LLVM.Native backend


Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info

FFT components for the Accelerate language

GitHub CI Gitter
Stackage LTS Stackage Nightly Hackage

FFT library for the embedded array language Accelerate. For details on Accelerate, refer to the main repository.

The following build flags control whether optimised implementations are used. Note that enabling these (which is the default) will require the corresponding Accelerate backend as a dependency:

  • llvm-ptx: For NVIDIA GPUs
  • llvm-cpu: For multicore CPUs
