Struct StabilityAnalysis 

pub struct StabilityAnalysis {
    pub eigenvalues: Vec<(f64, f64)>,
}

Stability analysis via eigenvalues (real_part, imag_part).

Fields

eigenvalues: Vec<(f64, f64)>

Eigenvalues as (real part, imaginary part) pairs

Implementations

impl StabilityAnalysis

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

Create from a list of (real, imag) eigenvalue pairs.

pub fn is_stable(&self) -> bool

Lyapunov stable: all eigenvalues have non-positive real parts.

pub fn is_asymptotically_stable(&self) -> bool

Asymptotically stable: all eigenvalues have strictly negative real parts.

pub fn lyapunov_criterion(&self) -> String

Lyapunov criterion: the equilibrium is stable iff all eigenvalues have Re ≤ 0 (with non-strictly: marginal stability). Returns a descriptive string.
