Struct DualNumber 

pub struct DualNumber {
    pub real: f64,
    pub dual: f64,
}

A dual number a + ε b where ε² = 0.

Fields

real: f64

Real part.

dual: f64

Dual (infinitesimal) part.

Implementations

impl DualNumber

pub fn new(real: f64, dual: f64) -> Self

Creates a new dual number.

pub fn add(&self, other: &DualNumber) -> DualNumber

Component-wise addition.

pub fn mul(&self, other: &DualNumber) -> DualNumber

Dual-number multiplication: (a + εb)(c + εd) = ac + ε(ad + bc).

pub fn conjugate(&self) -> DualNumber

Dual conjugate (a, -b).

Trait Implementations

impl Clone for DualNumber

fn clone(&self) -> DualNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DualNumber

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

Formats the value using the given formatter.

impl PartialEq for DualNumber

fn eq(&self, other: &DualNumber) -> 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.
