shtns 3.6.1

High performance Spherical Harmonic Transform

This is the python module to use SHTns, a high performance spherical harmonic transform and rotation library. It requires FFTW installed in your system.

GETTING STARTED

Basic Installation:

• make sure FFTW is installed in your system; if not, install it using your system package manager.

• run:

  pip install shtns

This simple installation should work and be enough for most use cases. However, in order to have the highest possible performance, FFTW should be compiled and tuned for your machine, which is not the case with pre-compiled system packages.
