Struct TurningPointLocator 

pub struct TurningPointLocator {
    pub tol: f64,
    pub max_iter: usize,
}

Locator for turning (fold) points using bisection on the determinant.

Iteratively bisects between state_a (det > 0) and state_b (det < 0) to find the fold point to within tol in arc length.

Fields

tol: f64

Convergence tolerance on the determinant magnitude.

max_iter: usize

Maximum bisection iterations.

Implementations

impl TurningPointLocator

pub fn new(tol: f64, max_iter: usize) -> Self

Create a new TurningPointLocator.

pub fn locate( &self, state_a: &ContinuationState, state_b: &ContinuationState, jac: &dyn Fn(&[f64], f64) -> Vec<Vec<f64>>, ) -> (ContinuationState, f64)

Locate the turning point between state_a and state_b.

Returns the interpolated state closest to the fold, together with the determinant value at that state.
