Struct Integral 

pub struct Integral<N, P: FreeSizePolynomial<N> + Evaluable<N>> { /* private fields */ }

A type which intreprets a polynomial as an integral, and ensures consistent use of the underlying polynomial as an integral.

Implementations

impl<N, P: FreeSizePolynomial<N> + Evaluable<N>> Integral<N, P>

pub fn new(polynomial: P) -> Self

pub fn inner(&self) -> &P

impl<N, P: FreeSizePolynomial<N> + Evaluable<N> + Clone> Integral<N, P>

pub fn replace_c(&self, c: N) -> P

impl<N: Sub<Output = N>, P: FreeSizePolynomial<N> + Evaluable<N>> Integral<N, P>

pub fn eval(&self, start: N, end: N) -> N

Returns the area of the integral from the first point to the second point.

Example

use rustnomial::{Polynomial, Integrable};
let polynomial = Polynomial::new(vec![2.0, 1.0]);
let integral = polynomial.integral();
assert_eq!(2.0, integral.eval(0.0, 1.0));
assert_eq!(6.0, integral.eval(0.0, 2.0));
assert_eq!(4.0, integral.eval(1.0, 2.0));
