Struct StiffnessDetector 

pub struct StiffnessDetector<F: IntegrateFloat> { /* private fields */ }

Enhanced stiffness detector that uses multiple indicators

Implementations

impl<F: IntegrateFloat> StiffnessDetector<F>

pub fn new() -> Self

Create a new stiffness detector with default configuration

pub fn with_config(config: StiffnessDetectionConfig<F>) -> Self

Create a new stiffness detector with specific configuration

pub fn record_step( &mut self, step_size: F, error: F, newton_iterations: usize, rejected: bool, steps_taken: usize, )

Record a step for stiffness analysis

pub fn is_stiff( &self, _current_method_is_stiff: bool, steps_sinceswitch: usize, ) -> bool

Check if the problem is stiff based on collected indicators

pub fn reset_after_switch(&mut self)

Reset indicators after method switch

pub fn stiffness_score(&self) -> F

Get current stiffness score (-1.0 to 1.0, where positive means stiff)

pub fn estimate_stiffness_from_jacobian(&mut self, jacobian: &Array2<F>) -> F

Estimate stiffness ratio using eigenvalues of the Jacobian
