Struct EulerSolver

pub struct EulerSolver<'a, N, D, T, F>
where
    N: ComplexField + Copy,
    D: Dimension,
    T: Clone,
    F: Derivative<N, D, T> + 'a,
    DefaultAllocator: Allocator<N, D>,
{ /* private fields */ }

The struct that actually solves an IVP with Euler’s method Is the associated IVPStepper for Euler (the IVPSolver) You should use Euler and not this type directly

Trait Implementations

impl<'a, N, D, T, F> IVPStepper<D> for EulerSolver<'a, N, D, T, F>

where N: ComplexField + Copy, D: Dimension, T: Clone, F: Derivative<N, D, T> + 'a, DefaultAllocator: Allocator<N, 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, ) -> Result<(Self::RealField, BVector<Self::Field, D>), IVPStatus<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.
