SHTns

Release Notes: This release fixes problems with compilation, adds optional support for the fft provided by intel MKL, and allows multi-threaded and single-threaded libraries to be installed side-by-side. The multi-threaded fftw is detected more reliably. The timing program now works on MacOS X and requires less memory. There are also other minor fixes and improvements.

Release Notes: This release adds new functions to access more data structures (m, gauss nodes, etc.) and allows some special operators to be applied in spectral space without performing a transform (like multiplication by cos(theta)). There are also minor improvements and two important bugfixes (one specific to openmp, the other to clang).

Release Notes: This release applies the previous critical bugfix to the OpenMP parallel code.

Release Notes: This release fixes an imported bug which led to wrong results when computing gradients (functions SHtor_to_spat and SHsph_to_spat) with on-the-fly transforms. Other transform functions have been not affected, and only the on-the-fly algorithm was wrong for mmax > 0. All users should upgrade.

Release Notes: This minor release fixes a few bugs in the build system and comes with an improved Python interface, thanks to two new very simple methods, synth() and analys().
