Ordering option

Variants

Amd

Ordering using the approximate minimum degree

Amf

Ordering using the approximate minimum fill-in (MUMPS-only, otherwise Auto)

Auto

Automatic ordering method selection

Best

Try three methods and take the best (UMFPACK-only, otherwise Auto)

Cholmod

Use Amd for symmetric, Colamd for unsymmetric, or Metis (UMFPACK-only, otherwise Auto)

Colamd

Use the column approximate minimum degree ordering algorithm (KLU-only, otherwise Auto)

Metis

Ordering by Karpis & Kumar from the University of Minnesota

No

The matrix is factorized as-is (UMFPACK-only, otherwise Auto)

Pord

Ordering by Schulze from the University of Paderborn (MUMPS-only, otherwise Auto)

Qamd

Ordering using the automatic quasi-dense row detection (MUMPS-only, otherwise Auto)

Scotch

Ordering using the Scotch package (MUMPS-only, otherwise Auto)

Implementations

impl Ordering

pub fn from(ordering: &str) -> Self

Returns the Ordering by name (default is Auto)

Trait Implementations

impl Clone for Ordering

fn clone(&self) -> Ordering

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Ordering

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Ordering

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Ordering

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Ordering

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Ordering

impl Eq for Ordering

impl StructuralPartialEq for Ordering
