Struct OdeState 

pub struct OdeState {
    pub t: f64,
    pub y: Vec<f64>,
}

Combined time and state vector for an ODE system.

Stores the current time t and the state vector y, and provides convenience helpers such as the Euclidean norm of the state.

Fields

t: f64

Current time.

y: Vec<f64>

State vector y(t).

Implementations

impl OdeState

pub fn new(t: f64, y: Vec<f64>) -> Self

Construct a new OdeState from time t and state vector y.

pub fn norm(&self) -> f64

Euclidean norm of the state vector.

pub fn dim(&self) -> usize

Number of components in the state vector.

pub fn zeros(t: f64, n: usize) -> Self

Return a zero state of dimension n at time t.

pub fn lerp(&self, other: &OdeState, alpha: f64) -> OdeState

Component-wise linear interpolation between self and other at parameter alpha ∈ [0, 1].

Trait Implementations

impl Clone for OdeState

fn clone(&self) -> OdeState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OdeState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for OdeState

fn eq(&self, other: &OdeState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
