Struct MultiDual 

pub struct MultiDual { /* private fields */ }

Multi-dimensional dual number for computing gradients

Implementations

impl MultiDual

pub fn new(value: f64, derivatives: Array1<f64>) -> Self

Create a new multi-dimensional dual number

pub fn constant(value: f64, nvars: usize) -> Self

pub fn variable(value: f64, var_index: usize, nvars: usize) -> Self

Create a variable multi-dual (one derivative = 1, others = 0)

pub fn value(&self) -> f64

Get the function value

pub fn gradient(&self) -> &Array1<f64>

Get the gradient

pub fn partial(&self, index: usize) -> f64

Get a specific partial derivative
