Non-uniform fast Fourier transforms on the GPU
Project description
cuFINUFFT v2.2 Python package
The cuFINUFFT library is an efficient GPU implementation of the 1-, 2- and 3-dimensional nonuniform fast Fourier transform (NUFFT). It includes both type 1 (nonuniform to uniform) and type 2 (uniform to nonuniform) transforms. It is based on the FINUFFT implementation for the CPU. This package provides a Python interface to the cuFINUFFT library, which is written in C++ and CUDA.
For a mathematical description of the NUFFT and applications to signal processing, imaging, and scientific computing, see the FINUFFT documentation. Usage examples can be found here.
If you use this package, please cite our paper:

Note: With version 2.2 of cuFINUFFT, we have changed the interfaces slightly to better align with FINUFFT. For an outline of the changes, please see the migration guide.
