Struct nalgebra_lapack::Schur

pub struct Schur<N: Scalar, D: Dim> where
    DefaultAllocator: Allocator<N, D> + Allocator<N, D, D>,  { /* fields omitted */ }

Eigendecomposition of a real square matrix with real eigenvalues.

Methods

impl<N: SchurScalar + RealField, D: Dim> Schur<N, D> where
    DefaultAllocator: Allocator<N, D, D> + Allocator<N, D>, 

pub fn new(m: MatrixN<N, D>) -> Self

Computes the eigenvalues and real Schur form of the matrix m.

Panics if the method did not converge.

pub fn try_new(m: MatrixN<N, D>) -> Option<Self>

Computes the eigenvalues and real Schur form of the matrix m.

Returns None if the method did not converge.

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

Retrieves the unitary matrix Q and the upper-quasitriangular matrix T such that the decomposed matrix equals Q * T * Q.transpose().

pub fn eigenvalues(&self) -> Option<VectorN<N, D>>

Computes the real eigenvalues of the decomposed matrix.

Return None if some eigenvalues are complex.

pub fn complex_eigenvalues(&self) -> VectorN<Complex<N>, D> where
    DefaultAllocator: Allocator<Complex<N>, D>, 

Computes the complex eigenvalues of the decomposed matrix.
