Hessenberg decomposition of a general matrix.

Implementations

source

impl<T, D> Hessenberg<T, D> where
 T: ComplexField,
 D: DimSub<Const<1_usize>>,
 DefaultAllocator: Allocator<T, D, D>,
 DefaultAllocator: Allocator<T, D, Const<1_usize>>,
 DefaultAllocator: Allocator<T, <D as DimSub<Const<1_usize>>>::Output, Const<1_usize>>,

source

pub fn new(
hess: Matrix<T, D, D, <DefaultAllocator as Allocator<T, D, D>>::Buffer>
) -> Hessenberg<T, D>

Computes the Hessenberg decomposition using householder reflections.

source

pub fn new_with_workspace(
hess: Matrix<T, D, D, <DefaultAllocator as Allocator<T, D, D>>::Buffer>,
work: &mut Matrix<T, D, Const<1_usize>, <DefaultAllocator as Allocator<T, D, Const<1_usize>>>::Buffer>
) -> Hessenberg<T, D>

Computes the Hessenberg decomposition using householder reflections.

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

source

pub fn unpack(
self
) -> (Matrix<T, D, D, <DefaultAllocator as Allocator<T, D, D>>::Buffer>, Matrix<T, D, D, <DefaultAllocator as Allocator<T, D, D>>::Buffer>)

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

source

pub fn unpack_h(
self
) -> Matrix<T, D, D, <DefaultAllocator as Allocator<T, D, D>>::Buffer>

Retrieves the upper trapezoidal submatrix H of this decomposition.

source

pub fn h(
&self
) -> Matrix<T, D, D, <DefaultAllocator as Allocator<T, D, D>>::Buffer>

Retrieves the upper trapezoidal submatrix H of this decomposition.

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

source

pub fn q(
&self
) -> Matrix<T, D, D, <DefaultAllocator as Allocator<T, D, D>>::Buffer>

Computes the orthogonal matrix Q of this decomposition.
