Struct Rk4Solver &nbsp; Copy item path

impl<S: OdeSystem> Rk4Solver<S>

pub fn new(system: S, step_size: f64) -> Self

Creates a new RK4 solver with given step size

pub fn solve(&mut self, t_start: f64, t_end: f64, y0: f64) -> f64

Solves the ODE from t_start to t_end

§Arguments

t_start - Starting time
t_end - Ending time
y0 - Initial state

§Returns

Final state vector after integration

pub fn step(&mut self, t: f64, y: f64, h: f64) -> f64

Performs a single RK4 step

RK4 coefficients: k1 = f(t, y) k2 = f(t + h/2, y + hk1/2) k3 = f(t + h/2, y + hk2/2) k4 = f(t + h, y + h*k3) y_{n+1} = y_n + (h/6)(k1 + 2k2 + 2k3 + k4)

pub fn step_gpu( &mut self, _integrator: &mut PlatformGpuIntegrator, t: f64, y: f64, h: f64, ) -> Result<f64, GpuError>

Performs RK4 step using GPU acceleration

Offloads the k1-k4 computations to the GPU via PlatformGpuIntegrator

pub fn step_quin(&mut self, quin: NQuin, h: f64) -> NQuin

Performs RK4 step directly on a Quin

This is the dispatcher-integrated version that takes a Quin, extracts the ODE state, performs the RK4 step, and returns a new Quin with the updated state.

§Arguments

quin - Input Quin with ODE state packed in object/metadata fields
h - Step size

§Returns

New Quin with updated ODE state

pub fn step_quin_gpu( &mut self, integrator: &mut PlatformGpuIntegrator, quin: NQuin, h: f64, ) -> Result<NQuin, GpuError>

Performs RK4 step on Quin using GPU acceleration

Dispatcher-integrated version with GPU support

pub fn reset_compensation(&mut self)

Resets Kahan compensation accumulator

pub fn compensation(&self) -> f64

Gets current Kahan compensation value
