Project description

Flatiron Institute Nonuniform Fast Fourier Transform library: FINUFFT

Principal author Alex H. Barnett, main co-developers Jeremy F. Magland, Ludvig af Klinteberg, Yu-hsuan "Melody" Shih, Andrea Malleo, Libin Lu, Joakim Andén, Marco Barbone, and Robert Blackwell.

This package provides a Python interface to the CPU library, enabling fast computation of nonuniform discrete Fourier transforms to specified precision in one, two, and three dimensions. It supports transforms of type 1 (nonuniform to uniform), type 2 (uniform to nonuniform) and type 3 (nonuniform to nonuniform). For more information, see the online documentation.
