Struct EmbeddedRkError 

Source 
pub struct EmbeddedRkError;
Expand description

Embedded Runge-Kutta error estimator.

Uses two RK methods of different orders to estimate local truncation error. Example: RK4 (order 4) and RK5 (order 5) for error estimation.

Implementations§

Source§

impl EmbeddedRkError

Source

pub fn estimate( model: &Model, state: &State, derivatives_fn: impl Fn(&Model, &State) -> (DVec, DVec), ) -> f64

Estimate error by comparing RK4 and RK5 solutions.

Returns maximum relative error over all state components.
