Type Definition num_dual::Dual

pub type Dual<T, F> = DualVec<T, F, 1>;

Implementations

impl<T, F> Dual<T, F>

pub fn new_scalar(re: T, eps: T) -> Self

Create a new scalar dual number from its fields.

impl<T: One, F> Dual<T, F>

pub fn derive(self) -> Self

Derive a scalar dual number, i.e. set the derivative part to 1.

let x = Dual64::from_re(5.0).derive().powi(2);
assert_eq!(x.re, 25.0);
assert_eq!(x.eps[0], 10.0);
