Function fang_oost::get_density

pub fn get_density<'a, 'b: 'a, S>(
    x_min: f64, 
    x_max: f64, 
    x_domain_iterator: S, 
    fn_inv_vec: &'b [Complex<f64>]
) -> impl IndexedParallelIterator<Item = f64> + 'a where
    S: IndexedParallelIterator<Item = f64> + Sync + 'b, 

Returns iterator over density with domain created by the function
