https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D223429 Bug ID: 223429 Summary: math/nfft 3.3.2: Nonequispaced fast Fourier transform Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: mike.d.ft402@gmail.com Created attachment 187728 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D187728&action= =3Dedit math/nfft /!\ At present this requres a patched libm to fix the missing cpow function: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221341 NFFT is a software library, written in C, for computing non-equispaced fast Fourier transforms and related variations. It implements the following transforms: 1. Non-equispaced fast Fourier transform (NFFT) - forward transform (NFFT), i.e. frequency to time/space domain - adjoint transform (adjoint NFFT), i.e. time/space to frequency domain 2. Generalisations - to arbitrary nodes in time and frequency domain (NNFFT) - to real-valued data, i.e. (co)sine transforms, (NFCT, NFST) - to the sphere S^2 (NFSFT) - to the rotation group (NFSOFT) - to the hyperbolic cross (NSFFT) 3. Generalised inverse transformations based on iterative methods, e.g. CGNR/CGNE --=20 You are receiving this mail because: You are the assignee for the bug.=
