pub struct CashKarp45 {}
CashKarp45
is a Runge Kutta Cash Karp integrator.
Trait Implementations
impl RK for CashKarp45
[src]
fn order() -> u8
[src]
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
fn stages() -> usize
[src]
Returns the stages of this integrator (as usize because it's used as indexing)
fn a_coeffs() -> &'static [f64]
[src]
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 more
fn b_coeffs() -> &'static [f64]
[src]
Returns a pointer to a list of f64 corresponding to the b_i and b^*_i coefficients of the Butcher table for that RK. Self.a_coeffs().len()
must be of size (order+1)*2. Read more
