Struct gauss_quad::Midpoint

pub struct Midpoint { /* fields omitted */ }

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);
