v2.1.0

FINUFFT version 2.1.0, with professionalized name-safe lib symbols and headers, and plenty of other improvements described in the CHANGELOG.

v2.0.4

Maintenance release: bug fixes, documentation improvements, cleaner Fortran examples. No changes in interface or performance.

v2.0.3

Finally thread-safety (enabled by -DFFTW_PLAN_SAFE, needs FFTW>=3.3.6, hence not yet enforced by default), plus a couple of important bug and doc fixes. See CHANGELOG.

v2.0.2 stable

FINUFFT v2.0.2 stable release.

See CHANGELOG for new features and changes.

If you have trouble compiling the library or especially language interfaces, you may want to check for binaries at https://users.flatironinstitute.org/~ahb/codes/finufft-binaries/

v1.1.2

stable 1/31/2020 release of FINUFFT.

Includes:
Ludvig af Klinteberg's Horner polynomial loop padding to w=4n for better SIMD vectorization on older GCC versions (pre-6).
Vineet Bansal's Mingw32 python patches.

For binaries, see https://users.flatironinstitute.org/ahb/public_www/codes/finufft-binaries/

If you have trouble with the upcoming v1.2, downgrade to this, and note that v1.2 changes a couple of interfaces.

v.1.1.1

This version improves upon 1.0 in terms of performance, mac OSX compatibility, C interface and header file simplicity, and documentation.
The only interface change is: setting default options
is via
nufft_opts opts; finufft_default_opts(&opts);
instead of
nufft_opts opts; finufft_default_opts(opts);
Ie, you have to insert one ampersand (see docs/).
See CHANGELOG.
For binaries, see https://users.flatironinstitute.org/ahb/public_www/codes/finufft-binaries/

v1.0

Version 1.0 of FINUFFT, including the nine basic interfaces, and 2d1many and 2d2many interfaces, for the CPU.
