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 checksums rmd160 08b4ff6b8d35b2ebc90159a8e86ff400e565528c \ sha256 74cc7f4c8922d72131c59f88ecb542e06254eaded09018d6367f8a46c0fb3125 depends_lib port:fftw-3 use_autoreconf no configure.args --enable-shared --enable-static --enable-all use_parallel_build yes test.run yes test.target check variant kaiserbessel description {compile with Kaiser-Bessel window (default)} conflicts gaussian bspline sinc { configure.args-append --with-window=kaiserbessel } variant gaussian description {compile with Gaussian window} conflicts kaiserbessel bspline sinc { configure.args-append --with-window=gaussian } variant bspline description {compile with B-Spline window} conflicts kaiserbessel gaussian sinc { configure.args-append --with-window=bspline } variant sinc description {compile with Sinc window} conflicts kaiserbessel gaussian bspline { configure.args-append --with-window=sinc } if {![variant_isset gaussian] && ![variant_isset bspline] && ![variant_isset sinc]} { default_variants-append +kaiserbessel }
