SSHT C documentation

The SSHT code provides functionality to perform fast and exact spin spherical harmonic transforms based on the sampling theorem on the sphere derived in our paper: A novel sampling theorem on the sphere (ArXiv | DOI). Functionality is also provided to perform fast and exact adjoint transforms based on the fast algorithms derived in our paper: Efficient and compressive sampling on the sphere.

We document the C source code here. For an example of usage, see the ssht_test.c program. For installation instructions, see the general SSHT documentation available here.
