Struct gramschmidt::Classical

pub struct Classical { /* fields omitted */ }

A classical Gram Schmidt factorization. See the Gram Schmidt Wikipedia entry for more information.

Use this struct via the GramSchmidt trait.

Trait Implementations

impl GramSchmidt for Classical

fn from_shape<T>(shape: T) -> Result<Self> where
    T: ShapeBuilder<Dim = Dim<[Ix; 2]>>, 

Reserves the memory for a QR decomposition via a classical Gram Schmidt orthogonalization using a shape.

fn compute<S>(&mut self, a: &ArrayBase<S, Ix2>) -> Result<()> where
    S: Data<Elem = f64>, 

Computes a QR decomposition using a Gram Schmidt orthonormalization of the matrix a.

fn q(&self) -> &Array2<f64>

Return a reference to the matrix q.

fn r(&self) -> &Array2<f64>

Return a reference to the matrix q.

fn compute_once<S>(a: &ArrayBase<S, Ix2>) -> Result<(Array2<f64>, Array2<f64>)> where
    S: Data<Elem = f64>, 

One-off version of [compute]. Takes the matrix a to be factorized, allocates a type implementing the GramSchmidt trait, computes the QR decomposition, and returns clones of the Q and R matrices.

fn from_matrix<S>(a: &ArrayBase<S, Ix2>) -> Result<Self> where
    S: Data<Elem = f64>, 

Uses a matrix to reserve memory for a QR decomposition via a classical Gram Schmidt.

impl Clone for Classical

fn clone(&self) -> Classical

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Classical

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

Formats the value using the given formatter.
