Trait System

pub trait System<T, V>
where
    T: FloatNumber,
{
    // Required method
    fn system(&self, x: T, y: &V, dy: &mut V);

    // Provided method
    fn solout(&mut self, _x: T, _y: &V, _dy: &V) -> bool { ... }
}

Trait needed to be implemented by the user

The type parameter T should be either f32 or f64, the trait FloatNumber is used internally to allow generic code.

The type parameter V is a state vector. To have an easy start it is recommended to use nalgebra vectors.

use ode_solvers::{System, SVector, Vector3};

// A predefined type for a vector (works from 1..6)
type Precision = f64;
type State = Vector3<Precision>;
type MySystem = dyn System<Precision, State>;

// Definition of a higher dimensional vector using nalgebra
type AltState = SVector<Precision, 9>;
type MyAltSystem = dyn System<Precision, State>;

Required Methods

fn system(&self, x: T, y: &V, dy: &mut V)

System of ordinary differential equations.

Provided Methods

fn solout(&mut self, _x: T, _y: &V, _dy: &V) -> bool

Stop function called at every successful integration step. The integration is stopped when this function returns true.
