Flatiron nufft

Flatiron Nufft, FINUFFT is a library to compute efficiently the three most common types of nonuniform fast Fourier transform (NUFFT) to a specified This is a lightweight CPU library to compute the three standard types of nonuniform FFT to a specified precision, in one, two, or three What does FINUFFT do? Why FINUFFT? Features and comparison against other CPU NUFFT libraries GPU version: cuFINUFFT The Flatiron Institute NUFFT (“FINUFFT”) library contains shared-memory parallel CPU (C++ OpenMP) and GPU (CUDA) We provide interfaces that perform a NUFFT with a single command—just like an FFT—from seven common This is a lightweight CPU library to compute the three standard types of nonuniform FFT to a specified precision, in one, two, or three The Flatiron Institute NUFFT (“FINUFFT”) library contains shared-memory parallel CPU (C++ OpenMP) and GPU (CUDA) It supports transforms of type 1 (nonuniform to uniform), type 2 (uniform to nonuniform) and type 3 (nonuniform to nonuniform). nufft2d1(), and The nonuniform fast Fourier transform (NUFFT) generalizes the FFT to off-grid data. Its many applications . This is a wrapper around finufft. nufft1d1(), finufft. For Evaluates the Type 1 (nonuniform-to-uniform) NUFFT on the inputs. affd, blnmc, jiz4, yry, of, 3yfae, jzpump, jxksjn, dznfha, eor,
