Struct nalgebra::linalg::Hessenberg [−][src]
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]
DefaultAllocator: Allocator<N, D, D> + Allocator<N, D> + Allocator<N, DimDiff<D, U1>>,
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.
