description Fast C routines to compute the Non-equispaced Discrete Fourier Transform
long_description NFFT3 is a software library written in C for computing nonequispaced fast Fourier \n\
and related transformations. In detail, NFFT3 implements \n\
1) The nonequispaced fast Fourier transform (NFFT) \n\
- the forward transform (NFFT) \n\
- the adjoint transform (adjoint NFFT) \n\
2) Generalisations of the NFFT \n\
- to arbitrary knots in time and frequency domain (NNFFT) \n\
- to the sphere S^2 (NFSFT) \n\
- to the hyperbolic cross (NSFFT) \n\
- to real-valued data, i.e. (co)sine transforms, (NFCT, NFST) \n\
- to the rotation group (NFSOFT) \n\
3) Generalised inverses based on iterative methods, e.g. CGNR, CGNE \n\
4) Applications in \n\
- medical imaging \n\
* magnetic resonance imaging \n\
* computerised tomography \n\
- summation schemes \n\
* fast Gauss transform (FGT) \n\
* singular kernels \n\
* zonal kernels \n\
- polar FFT, discrete Radon transform, ridgelet transform
