Struct DualVec 

pub struct DualVec {
    pub components: Vec<Dual>,
}

A vector of Dual numbers for multivariate forward-mode differentiation.

Fields

components: Vec<Dual>

The dual components.

Implementations

impl DualVec

pub fn from_pairs(pairs: &[(f64, f64)]) -> Self

Construct from a slice of (value, derivative) pairs.

pub fn variable(xs: &[f64], seed_idx: usize) -> Self

Construct a variable vector: component i has seed 1, others 0.

pub fn len(&self) -> usize

Length of the vector.

pub fn is_empty(&self) -> bool

Returns true if the vector is empty.
