WebDescription: FINUFFT is a set of libraries to compute efficiently three types of nonuniform fast Fourier transform (NUFFT) to a specified precision, in one, two, or three dimensions, on a multi-core shared-memory machine. The library has a very simple interface, does not need any precomputation step, is written in C++ (using OpenMP and FFTW ... WebOverview¶. FINUFFT is a multi-threaded library to compute efficiently the three most common types of nonuniform fast Fourier transform (NUFFT) to a specified precision, in …

All functions have double-precision ( finufft) and single-precision ( finufftf) versions. Do not forget this f suffix in the latter case. We group the simple and vectorized interfaces together, by each of the nine transform types (dimensions 1,2,3, and types 1,2,3).
WebQuick-start example in C++ ¶. Here’s how to perform a 1D type-1 transform in double precision from C++, using STL complex vectors. First include our header, and some others needed for the demo: #include "finufft.h" #include #include #include . We need nonuniform points x and complex strengths c.
