Struct Butterfly 

pub struct Butterfly;

Sum and difference of a two-element input.

This is the classic butterfly primitive used in lattice, complementary, and polyphase-style constructions. It is also the unnormalized 2-point Hadamard/Haar transform; apply any desired normalization outside the primitive.

Examples

use dsp_process::{Butterfly, Process};

assert_eq!(Butterfly.process([4, 1]), [5, 3]);
