Implementations

impl RetractionKind

pub fn euclidean(dim: usize) -> Self

pub fn ambient_dim(&self) -> usize

pub fn is_euclidean(&self) -> bool

pub fn metric_weights(&self) -> Vec<f64>

pub fn axis_periods(&self) -> Vec<Option<f64>>

Per-ambient-axis periodicity, mirroring [gam_terms::latent::LatentManifold::axis_periods]. A Circle retraction wraps modulo 2π; an embedded Sphere retraction is smooth with no cut and is reported non-periodic.

Trait Implementations

impl Clone for RetractionKind

fn clone(&self) -> RetractionKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RetractionKind

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

Formats the value using the given formatter.

impl PartialEq for RetractionKind

fn eq(&self, other: &RetractionKind) -> 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.

impl Retraction for RetractionKind

fn retract( &self, base: &mut ArrayViewMut1<'_, f64>, tangent: ArrayView1<'_, f64>, )
