Description-en: 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.
