Struct gauss_quad::Midpoint

pub struct Midpoint { /* private fields */ }

A midpoint rule quadrature scheme.

// initialize a midpoint rule with 100 cells
let quad: Midpoint = Midpoint::init(100);

// numerically integrate a function from -1.0 to 1.0 using the midpoint rule
let approx = quad.integrate(-1.0, 1.0, |x| x * x);

Implementations

impl Midpoint

pub fn init(degree: usize) -> Self

Initialize a new midpoint rule with degree number of cells.

Panics

Panics if degree is less than 1

pub fn integrate<F>(&self, a: f64, b: f64, integrand: F) -> f64where F: Fn(f64) -> f64,

Integrate over the domain [a, b].

Trait Implementations

impl Clone for Midpoint

fn clone(&self) -> Midpoint

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Midpoint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Midpoint

fn eq(&self, other: &Midpoint) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
