Struct BDFSolver

pub struct BDFSolver<'a, N, D, const O: usize, T, F>
where
    D: Dimension + DimMin<D, Output = D>,
    N: ComplexField + Copy,
    T: Clone,
    F: Derivative<N, D, T> + 'a,
    DefaultAllocator: Allocator<N, D> + Allocator<N, D, D>,
{ /* private fields */ }

The solver for any BDF predictor-corrector Users should not use this type directly, and should instead get it from a specific BDF method struct (wrapped in an IVPIterator)

Trait Implementations

impl<'a, N, D, const O: usize, T, F> IVPStepper<D> for BDFSolver<'a, N, D, O, T, F>

where N: ComplexField + Copy, D: Dimension + DimMin<D, Output = D>, T: Clone, F: Derivative<N, D, T> + 'a, DefaultAllocator: Allocator<N, D> + Allocator<N, U1, D> + Allocator<N, D, D> + Allocator<(usize, usize), D>,

type Error = IVPError

Error type. IVPError must be able to convert to the error type.

type Field = N

The field, complex or real, that the solver is operating on.

type RealField = <N as ComplexField>::RealField

The real field associated with the solver’s Field.

type UserData = T

Arbitrary data provided by the user for the derivative function It must be clone because for any intermediate time steps (e.g. in runge-kutta) gives the derivative function a clone of the params: only normal time steps get to update the internal UserData state

fn step(&mut self) -> Step<Self::RealField, Self::Field, D, Self::Error>

Step forward in the solver. The solver may request a step be redone, signal that the solution is finished, or give the value of the next solution value.

fn time(&self) -> Self::RealField

Get the current time of the solver.
