Fehlberg45
is a Runge Kutta Fehlberg integrator.
Trait Implementations
sourceimpl RK for Fehlberg45
impl RK for Fehlberg45
sourceconst ORDER: u8 = 5u8
const ORDER: u8 = 5u8
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 = 6usize
const STAGES: usize = 6usize
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

The inverse inclusion map: attempts to construct

superset. Read morefn is_in_subset(&self) -> bool

Checks if

Use with care! Same as

The inclusion map: converts
self
to the equivalent element of its superset.
