Struct SpectralDecomposition 

pub struct SpectralDecomposition {
    pub matrix: Vec<Vec<f64>>,
}

Spectral decomposition (eigendecomposition) of a real matrix.

Fields

matrix: Vec<Vec<f64>>

The matrix stored in row-major order.

Implementations

impl SpectralDecomposition

pub fn new(matrix: Vec<Vec<f64>>) -> Self

Create a new SpectralDecomposition.

pub fn eigenvalues(&self) -> Vec<f64>

Compute eigenvalues of a real symmetric matrix via the QR algorithm (simplified).

For a 1×1 or 2×2 matrix this is exact; for larger matrices we use 30 QR iterations.

pub fn eigenvectors(&self) -> Vec<Vec<f64>>

Return an identity-matrix approximation of the eigenvectors (placeholder).

pub fn is_symmetric(&self) -> bool

Check whether the matrix is symmetric (Aᵢⱼ = Aⱼᵢ).
