Enum EigenAlgorithm 

pub enum EigenAlgorithm {
    Auto,
    Lapack,
    Arpack,
    CompAuto,
    CompLapack,
    CompArpack,
}

Which numerical library eigen_matrix_symmetric, eigen_matrix and Graph::eigen_adjacency use (igraph_eigen_algorithm_t).

Variants

Auto

Choose automatically. For symmetric matrices: LAPACK when the matrix is small (n < 100), when as many eigenvalues as the order are requested, and for EigenWhich::All, EigenWhich::Interval and EigenWhich::Select (which only LAPACK supports); ARPACK otherwise. ARPACK for Graph::eigen_adjacency. Not implemented by igraph (1.0.0 and 1.0.1) for eigen_matrix.

Lapack

Dense LAPACK routines (the matrix is formed explicitly).

Arpack

ARPACK (matrix-free, only matrix-vector products).

CompAuto

Complex variant of Auto (not implemented by igraph 1.0.0 and 1.0.1).

CompLapack

Complex variant of Lapack (not implemented by igraph 1.0.0 and 1.0.1).

CompArpack

Complex variant of Arpack (not implemented by igraph 1.0.0 and 1.0.1).

Trait Implementations

impl Clone for EigenAlgorithm

fn clone(&self) -> EigenAlgorithm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EigenAlgorithm

impl Debug for EigenAlgorithm

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

Formats the value using the given formatter.

impl Eq for EigenAlgorithm

impl From<EigenAlgorithm> for igraph_eigen_algorithm_t

fn from(value: EigenAlgorithm) -> igraph_eigen_algorithm_t

Converts to this type from the input type.

impl Hash for EigenAlgorithm

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 EigenAlgorithm

fn eq(&self, other: &EigenAlgorithm) -> 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 StructuralPartialEq for EigenAlgorithm

impl TryFrom<u32> for EigenAlgorithm

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: igraph_eigen_algorithm_t) -> Result<Self>

Performs the conversion.
