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\ (i) magnetic resonance imaging \n\ (ii) computerised tomography \n\ - summation schemes \n\ (i) fast Gauss transform (FGT) \n\ (ii) singular kernels \n\ (iii) zonal kernels \n\ - polar FFT, discrete Radon transform, ridgelet transform homepage http://www.nfft.org master_sites https://github.com/NFFT/nfft/archive/ checksums rmd160 493e0bf58c8b48d8a7719c6d35c32977288f622f \ sha256 79086a5e4b394d0336237126fbba459e6d1f02ccfa0fef5f016d96dadfe8fac0 depends_lib port:fftw-3 use_autoreconf yes configure.args --enable-shared --enable-static --enable-all use_parallel_build yes 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 }
