Struct extendr_api::prelude::sparse::linalg::SupernodalThreshold

pub struct SupernodalThreshold(pub f64);

Nonnegative threshold controlling when the supernodal factorization is used.

Increasing it makes it more likely for the simplicial factorization to be used, while decreasing it makes it more likely for the supernodal factorization to be used.

A value of 1.0 is the default.

Tuple Fields

0: f64

Implementations

impl SupernodalThreshold

pub const FORCE_SIMPLICIAL: SupernodalThreshold = _

Simplicial factorization is always selected.

pub const FORCE_SUPERNODAL: SupernodalThreshold = _

Supernodal factorization is always selected.

pub const AUTO: SupernodalThreshold = _

Determine automatically which variant to select.

Trait Implementations

impl Clone for SupernodalThreshold

fn clone(&self) -> SupernodalThreshold

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SupernodalThreshold

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

Formats the value using the given formatter.

impl Default for SupernodalThreshold

fn default() -> SupernodalThreshold

Returns the “default value” for a type.

impl PartialEq for SupernodalThreshold

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