Topics

Here is a list of all topics with brief descriptions:

Spherical Harmonic transform functions.	All these function perform a global spherical harmonic transform
GPU transforms.	CUDA transforms working on GPU memory, without transfers, but NOT thread-safe
Initialization functions.
Fortran API.	Call from fortran without the trailing '_'
Pseudo-spectral rotations of Spherical Harmonic fields (deprecated).	deprecated use Rotations of Spherical Harmonic fields. instead
Special operators	Apply special operators in spectral space: multiplication by cos(theta), sin(theta).d/dtheta
Local and partial evaluation of SH fields.	These do only require a call to shtns_create, but not to shtns_set_grid
Rotations of Spherical Harmonic fields.	Rotation of spherical harmonics, using an on-the-fly algorithm (does not store the rotation matrix) inspired by the GUMEROV's algorithm to generate the Wigner-d matrices describing rotation of Spherical Harmonics
