Function fang_oost::get_density

pub fn get_density<'a, 'b: 'a, T>(
    num_u: usize, 
    x: &'b [f64], 
    fn_inv: T
) -> impl IndexedParallelIterator<Item = f64> + 'a where
    T: Fn(&Complex<f64>) -> Complex<f64> + Sync + Send + 'a, 

Returns iterator over density from user supplied domain

Remarks

The endpoints of the x vector should have a large enough domain for accuracy.

Examples

extern crate num_complex;
use num_complex::Complex;
extern crate fang_oost;
let x = vec![-20.0, 3.0, 25.0];
let num_u = 256;
let mu = 2.0;
let sigma = 5.0;
let norm_cf = |u:&Complex<f64>|(u*mu+0.5*u*u*sigma*sigma).exp();
let density = fang_oost::get_density(
   num_u, &x, &norm_cf
);
