Struct peroxide::numerical::ode::GL4

pub struct GL4 {
    pub solver: ImplicitSolver,
    pub tol: f64,
    pub max_step_iter: usize,
}

Gauss-Legendre 4th order integrator.

This integrator uses the 4th order Gauss-Legendre Runge-Kutta method, which is an implicit integrator. It requires solving a system of nonlinear equations at each step, which is done using the specified implicit solver (e.g., fixed-point iteration). The Gauss-Legendre method has better stability properties compared to explicit methods, especially for stiff ODEs.

Member variables

• solver: The implicit solver to use.
• tol: The tolerance for the implicit solver.
• max_step_iter: The maximum number of iterations for the implicit solver per step.
