Struct Type4Naive 

pub struct Type4Naive<T> { /* private fields */ }

Naive O(n^2 ) DCT Type 4 and DST Type 4 implementation

// Computes a naive DCT4 of size 23
use rustdct::{Dct4, Dst4};
use rustdct::algorithm::Type4Naive;

let len = 23;
let naive = Type4Naive::new(len);

let mut dct4_buffer:  Vec<f32> = vec![0f32; len];
naive.process_dct4(&mut dct4_buffer);

let mut dst4_buffer:  Vec<f32> = vec![0f32; len];
naive.process_dst4(&mut dst4_buffer);
