Struct StabilityAnalysis 

Source 
pub struct StabilityAnalysis {
    pub marginal_tol: f64,
}
Expand description

Stability analysis along a continuation branch.

Evaluates the Jacobian eigenvalue structure at each ContinuationState in a sequence and assigns a stability label.

Fields§

§marginal_tol: f64

Tolerance for detecting marginal (near-zero real part) eigenvalues.

Implementations§

Source§

impl StabilityAnalysis

Source

pub fn new(marginal_tol: f64) -> Self

Create a new stability analyser.

Source

pub fn label( &self, state: &ContinuationState, jac: &dyn Fn(&[f64], f64) -> Vec<Vec<f64>>, ) -> StabilityLabel

Assign a stability label to a single state.

Uses the exact 2×2 formula and Gershgorin for larger systems.

Source

pub fn label_branch( &self, states: &[ContinuationState], jac: &dyn Fn(&[f64], f64) -> Vec<Vec<f64>>, ) -> Vec<StabilityLabel>

Label a sequence of states along a branch.
