Enum SphereSpectralKernelKind 

pub enum SphereSpectralKernelKind {
    Sobolev,
    Pseudo,
}

Which truncated-spectral Wahba kernel to evaluate on device. Matches the CPU SphereWahbaKernel::{SobolevTruncated, PseudoTruncated} so parity tests are well-defined.

Variants

Sobolev

c_ℓ = (2ℓ+1) / (4π · [ℓ(ℓ+1)]^m) — true H^m(S²) Sobolev RKHS.

Pseudo

c_ℓ = 2 / (4π · Π_{k=1..m+1}(ℓ + k)) — Wahba 1981 pseudo-spline.

Implementations

impl SphereSpectralKernelKind

pub fn coefficients(self, lmax: usize, m: usize) -> Vec<f64>

c_0 = 0, c_ℓ = c_ℓ(m) for ℓ = 1..=lmax. Returned vector has length lmax + 1 and is uploaded verbatim to constant/global memory before kernel launch.

pub const fn tag(self) -> &'static str

Stable string tag used in the NVRTC module cache key + logs.

Trait Implementations

impl Clone for SphereSpectralKernelKind

fn clone(&self) -> SphereSpectralKernelKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SphereSpectralKernelKind

impl Debug for SphereSpectralKernelKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for SphereSpectralKernelKind

impl Hash for SphereSpectralKernelKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SphereSpectralKernelKind

fn eq(&self, other: &SphereSpectralKernelKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
