Description: library for computing non-uniform Fourier transforms (double precision)
 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 double precision.
