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