Struct nyx_space::propagators::RK2Fixed
source · pub struct RK2Fixed {}
Expand description
RK2Fixed
is a fixed step RK4 (or midpoint method).
If initialized with an PropOpts.with_adaptive_step
, the variable step will not be taken into consideration.
Trait Implementations
sourceimpl RK for RK2Fixed
impl RK for RK2Fixed
sourceconst ORDER: u8 = 2u8
const ORDER: u8 = 2u8
Returns the order of this integrator (as u8 because there probably isn’t an order greater than 255).
The order is used for the adaptive step size only to compute the error between estimates. Read more
sourceconst STAGES: usize = 2usize
const STAGES: usize = 2usize
Returns the stages of this integrator (as usize because it’s used as indexing)
sourceconst A_COEFFS: &'static [f64] = _
const A_COEFFS: &'static [f64] = _
Returns a pointer to a list of f64 corresponding to the A coefficients of the Butcher table for that RK.
This module only supports implicit integrators, and as such,
Self.a_coeffs().len()
must be of
size (order+1)*(order)/2.
Warning: this RK trait supposes that the implementation is consistent, i.e. c_i = \sum_j a_{ij}. Read moreAuto Trait Implementations
