WebSep 2, 2024 · Consider a perturbation δ A in your matrix A —with double-precision floats this is O ( 10 − 16). It turns the eigendecomposition from X − 1 A X = Λ into (approximately keeping X fixed) X − 1 ( A + δ A) X = Λ + δ Λ. This means that the change in eigenvalues is bounded by ‖ δ Λ ‖ ≤ ‖ X − 1 ‖ ‖ X ‖ ‖ δ A ‖ = κ ( X) ‖ δ A ‖,
