Python wrapper for the NFFT library

See the pynfft by G. Vaillant.

For Matlab and Octave

For Linux and macOS, please download nfft-3.4.*.tar.gz and compile with mex interface support (see ./configure --help).
For Windows, ready-to-use mex interfaces can be found on the download page.

For Mathematica

A Mathematica implementation for performing the NFFT as well as a Mathematica notebook demonstrating the use of the package written by Sseziwa Mukasa (mukasa(AT)jeol.com) can be downloaded.

For Julia

A Julia implementation for performing the NFFT written by Tobias Knopp see.

For Windows & Visual C

The NFFT2.0 is also available for Windows as Visual C project by Eskofier Bjoern (bjoern.eskofier(AT)gmx.de).
Using the NFFT3.0 for Windows see the FAQ.

Methods, similar to the NFFT, are known as

  • unequally-spaced fast Fourier transform (USFFT by G. Beylkin).
  • generalized fast Fourier transform (GFFT by A. Dutt and V. Rokhlin),
  • nonuniform fast Fourier transform (NUFFT by J.A. Fessler and B.P. Sutton),
  • nonequispaced fast Fourier transform NFFT by K. Fourmount),
  • irregularly spaced data analysis (ISDA by J. Pelt)
