| 15 | description Fast C routines to compute the Non-equispaced Discrete Fourier Transform |
|---|
| 16 | long_description NFFT3 is a software library written in C for computing nonequispaced fast Fourier \n\ |
|---|
| 17 | and related transformations. In detail, NFFT3 implements \n\ |
|---|
| 18 | 1) The nonequispaced fast Fourier transform (NFFT) \n\ |
|---|
| 19 | - the forward transform (NFFT) \n\ |
|---|
| 20 | - the adjoint transform (adjoint NFFT) \n\ |
|---|
| 21 | 2) Generalisations of the NFFT \n\ |
|---|
| 22 | - to arbitrary knots in time and frequency domain (NNFFT) \n\ |
|---|
| 23 | - to the sphere S^2 (NFSFT) \n\ |
|---|
| 24 | - to the hyperbolic cross (NSFFT) \n\ |
|---|
| 25 | - to real-valued data, i.e. (co)sine transforms, (NFCT, NFST) \n\ |
|---|
| 26 | - to the rotation group (NFSOFT) \n\ |
|---|
| 27 | 3) Generalised inverses based on iterative methods, e.g. CGNR, CGNE \n\ |
|---|
| 28 | 4) Applications in \n\ |
|---|
| 29 | - medical imaging \n\ |
|---|
| 30 | * magnetic resonance imaging \n\ |
|---|
| 31 | * computerised tomography \n\ |
|---|
| 32 | - summation schemes \n\ |
|---|
| 33 | * fast Gauss transform (FGT) \n\ |
|---|
| 34 | * singular kernels \n\ |
|---|
| 35 | * zonal kernels \n\ |
|---|
| 36 | - polar FFT, discrete Radon transform, ridgelet transform |
