Struct sir_ddft::SIRDiffusion1DIVP

pub struct SIRDiffusion1DIVP { /* fields omitted */ }

Initial value problem for the SIR model with diffusion in one spatial dimension

Note: The model is technically a PDE, but is transformed to a high-dimensional ODE via the finite difference method.

Implementations

impl SIRDiffusion1DIVP

pub fn new(
    sir_params: SIRParameters,
    diff_params: SIRDiffusionParameters,
    state: SIRStateSpatial1D
) -> Self

Creates a new IVP for the SIR diffusion model

pub fn add_time(&mut self, time: f64)

Increase integration time

pub fn get_result(&self) -> (f64, SIRStateSpatial1DBorrowed<'_>)

Get current time and state

Note that the type of the return value is not SIRStateSpatial1D, but a similar construct with references

Trait Implementations

impl<S> ODEIVP<S> for SIRDiffusion1DIVP

fn rhs(&mut self, _: f64, y: &[f64]) -> Vec<f64>

Returns right hand side (i.e. the value of f) of IVP y'=f(t,y)

fn initial_state(&mut self) -> (f64, Vec<f64>)

Returns initial state (t_0, y_0) such that y(t_0) = y_0

fn end_step(&mut self, _: f64, _: &[f64], _: &S) -> StopCondition

Called at the end of each integration step (and once for t_0)

fn final_state(&mut self, t: f64, y: Vec<f64>)

Called at the end of integration giving back the state taken in initial_state
