Struct nalgebra_lapack::Eigen

pub struct Eigen<N: Scalar, D: Dim> where
    DefaultAllocator: Allocator<N, D> + Allocator<N, D, D>,  {
    pub eigenvalues: VectorN<N, D>,
    pub eigenvectors: Option<MatrixN<N, D>>,
    pub left_eigenvectors: Option<MatrixN<N, D>>,
}

Eigendecomposition of a real square matrix with real eigenvalues.

Fields

eigenvalues: VectorN<N, D>

The eigenvalues of the decomposed matrix.

eigenvectors: Option<MatrixN<N, D>>

The (right) eigenvectors of the decomposed matrix.

left_eigenvectors: Option<MatrixN<N, D>>

The left eigenvectors of the decomposed matrix.

Methods

impl<N: EigenScalar + Real, D: Dim> Eigen<N, D> where
    DefaultAllocator: Allocator<N, D, D> + Allocator<N, D>, 

pub fn new(
    m: MatrixN<N, D>,
    left_eigenvectors: bool,
    eigenvectors: bool
) -> Option<Eigen<N, D>>

Computes the eigenvalues and eigenvectors of the square matrix m.

If eigenvectors is false then, the eigenvectors are not computed explicitly.

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

The complex eigenvalues of the given matrix.

Panics if the eigenvalue computation does not converge.

pub fn determinant(&self) -> N

The determinant of the decomposed matrix.
