pub struct Hessenberg<T, D>where
    T: ComplexField,

Implementations

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

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.

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

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.

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.

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.

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

Computes the orthogonal matrix Q of this decomposition.
