Struct nalgebra::linalg::Hessenberg[][src]

pub struct Hessenberg<N: ComplexField, D: DimSub<U1>> where
    DefaultAllocator: Allocator<N, D, D> + Allocator<N, DimDiff<D, U1>>, 
{ /* fields omitted */ }

Hessenberg decomposition of a general matrix.

Implementations

impl<N: ComplexField, D: DimSub<U1>> Hessenberg<N, D> where
    DefaultAllocator: Allocator<N, D, D> + Allocator<N, D> + Allocator<N, DimDiff<D, U1>>, 
[src]

pub fn new(hess: MatrixN<N, D>) -> Self[src]

Computes the Hessenberg decomposition using householder reflections.

pub fn new_with_workspace(hess: MatrixN<N, D>, work: &mut VectorN<N, D>) -> Self[src]

Computes the Hessenberg decomposition using householder reflections.

The workspace containing D elements must be provided but its content does not have to be initialized.

pub fn unpack(self) -> (MatrixN<N, D>, MatrixN<N, D>)[src]

Retrieves (q, h) with q the orthogonal matrix of this decomposition and h the hessenberg matrix.

pub fn unpack_h(self) -> MatrixN<N, D>[src]

Retrieves the upper trapezoidal submatrix H of this decomposition.

pub fn h(&self) -> MatrixN<N, D>[src]

Retrieves the upper trapezoidal submatrix H of this decomposition.

This is less efficient than .unpack_h() as it allocates a new matrix.

pub fn q(&self) -> MatrixN<N, D>[src]

Computes the orthogonal matrix Q of this decomposition.
