library for computing non-uniform Fourier transforms
NFFT3 is a software library written in C for computing nonequispaced fast Fourier and related transformations. In detail, NFFT3 implements:
1) The nonequispaced fast Fourier transform (NFFT)
- the forward transform (NFFT) - the adjoint transform (adjoint NFFT)
2) Generalisations of the NFFT
- to arbitrary knots in time and frequency domain (NNFFT) - to the sphere S^2 (NFSFT) - to the hyperbolic cross (NSFFT) - to real-valued data, i.e. (co)sine transforms, (NFCT, NFST) - to the rotation group (NFSOFT)
3) Generalised inverses based on iterative methods, e.g. CGNR, CGNE
4) Applications in
- medical imaging
(i) magnetic resonance imaging
(ii) computerised tomography
- summation schemes
(i) fast Gauss transform (FGT)
(ii) singular kernels
(iii) zonal kernels
- polar FFT, discrete Radon transform, ridgelet transform
This package is a transitional package providing the NFFT library in all available precisions.
