Step size h

§tol: f64

Newton iteration tolerance

Implementations§

Source§

impl StiffSolver

Source

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

Create with given step size and tolerance.

Source

pub fn step(&self, f: &dyn Fn(f64, f64) -> f64, t: f64, y: f64) -> f64

Perform one backward Euler step via fixed-point iteration.

Source

pub fn solve_to( &self, f: &dyn Fn(f64, f64) -> f64, t0: f64, y0: f64, t_end: f64, ) -> Vec<(f64, f64)>

Solve from t0 to t_end using backward Euler.
