[][src]Struct nalgebra::linalg::SymmetricEigen

pub struct SymmetricEigen<N: ComplexField, D: Dim> where
    DefaultAllocator: Allocator<N, D, D> + Allocator<N::RealField, D>, 
{ pub eigenvectors: MatrixN<N, D>, pub eigenvalues: VectorN<N::RealField, D>, }

Eigendecomposition of a symmetric matrix.

Fields

eigenvectors: MatrixN<N, D>

The eigenvectors of the decomposed matrix.

eigenvalues: VectorN<N::RealField, D>

The unsorted eigenvalues of the decomposed matrix.

Methods

impl<N: ComplexField, D: Dim> SymmetricEigen<N, D> where
    DefaultAllocator: Allocator<N, D, D> + Allocator<N::RealField, D>, 
[src]

pub fn new(m: MatrixN<N, D>) -> Self where
    D: DimSub<U1>,
    DefaultAllocator: Allocator<N, DimDiff<D, U1>> + Allocator<N::RealField, DimDiff<D, U1>>, 
[src]

Computes the eigendecomposition of the given symmetric matrix.

Only the lower-triangular parts (including its diagonal) of m is read.

pub fn try_new(
    m: MatrixN<N, D>,
    eps: N::RealField,
    max_niter: usize
) -> Option<Self> where
    D: DimSub<U1>,
    DefaultAllocator: Allocator<N, DimDiff<D, U1>> + Allocator<N::RealField, DimDiff<D, U1>>, 
[src]

Computes the eigendecomposition of the given symmetric matrix with user-specified convergence parameters.

Only the lower-triangular part (including its diagonal) of m is read.

Arguments

  • eps − tolerance used to determine when a value converged to 0.
  • max_niter − maximum total number of iterations performed by the algorithm. If this number of iteration is exceeded, None is returned. If niter == 0, then the algorithm continues indefinitely until convergence.

pub fn recompose(&self) -> MatrixN<N, D>[src]

Rebuild the original matrix.

This is useful if some of the eigenvalues have been manually modified.
