cufinufft 1.3

Non-uniform fast Fourier transforms on the GPU

cuFINUFFT v1.3 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.

Note: We are currently in the process of adapting the cuFINUFFT interface to closer match that of FINUFFT. This will likely break code depending on the current interface once the next release is published. At this point we will publish a migration guide that will detail the exact changes to the interfaces.
