Function winter_math::polynom::eval

pub fn eval<B, E>(p: &[B], x: E) -> E where
    B: FieldElement,
    E: FieldElement + From<B>, 

Evaluates a polynomial at a single point and returns the result.

Evaluates polynomial p at coordinate x using Horner’s method.

Examples

// define polynomial: f(x) = 3 * x^2 + 2 * x + 1
let p = (1u32..4).map(BaseElement::from).collect::<Vec<_>>();

// evaluate the polynomial at point 4
let x = BaseElement::new(4);
assert_eq!(BaseElement::new(57), eval(&p, x));
