libnfft3-long2

library for computing non-uniform Fourier transforms (long-double precision)

Description

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 provides the shared library compiled with long-double precision.
