Result of hermitian_lanczos_lowest_eigenpair.

Contains the lowest Ritz eigenpair, the final true residual norm, iteration count, and convergence status.

Examples

use tensor4all_core::krylov::HermitianLanczosResult;

let result = HermitianLanczosResult {
    eigenvalue: 1.0,
    eigenvector: vec![1.0_f64],
    iterations: 1,
    residual_norm: 0.0,
    converged: true,
};
assert!(result.converged);
assert_eq!(result.eigenvalue, 1.0);
