[][src]Struct na::linalg::Hessenberg

pub struct Hessenberg<N, D> where
    D: DimSub<U1>,
    N: ComplexField,

Hessenberg decomposition of a general matrix.

Methods

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

pub fn new(
    hess: Matrix<N, D, D, <DefaultAllocator as Allocator<N, D, D>>::Buffer>
) -> Hessenberg<N, D>
[src]

Computes the Hessenberg decomposition using householder reflections.

pub fn new_with_workspace(
    hess: Matrix<N, D, D, <DefaultAllocator as Allocator<N, D, D>>::Buffer>,
    work: &mut Matrix<N, D, U1, <DefaultAllocator as Allocator<N, D, U1>>::Buffer>
) -> Hessenberg<N, D>
[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
) -> (Matrix<N, D, D, <DefaultAllocator as Allocator<N, D, D>>::Buffer>, Matrix<N, D, D, <DefaultAllocator as Allocator<N, D, D>>::Buffer>)
[src]

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

pub fn unpack_h(
    self
) -> Matrix<N, D, D, <DefaultAllocator as Allocator<N, D, D>>::Buffer>
[src]

Retrieves the upper trapezoidal submatrix H of this decomposition.

pub fn h(
    &self
) -> Matrix<N, D, D, <DefaultAllocator as Allocator<N, D, D>>::Buffer>
[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
) -> Matrix<N, D, D, <DefaultAllocator as Allocator<N, D, D>>::Buffer>
[src]

Computes the orthogonal matrix Q of this decomposition.
