Struct rustdct::algorithm::Dst1Naive

pub struct Dst1Naive<T> { /* fields omitted */ }

Naive O(n^2 ) DST Type 1 implementation

This implementation is primarily used to test other DST1 algorithms.

// Computes a naive DST1 of size 23
use rustdct::Dst1;
use rustdct::algorithm::Dst1Naive;

let len = 23;

let dst = Dst1Naive::new(len);

let mut buffer = vec![0f32; len];
dst.process_dst1(&mut buffer);

Implementations

impl<T: DctNum> Dst1Naive<T>

pub fn new(len: usize) -> Self

Creates a new DST1 context that will process signals of length len

Trait Implementations

impl<T: DctNum> Dst1<T> for Dst1Naive<T>

pub fn process_dst1_with_scratch(&self, buffer: &mut [T], scratch: &mut [T])

Computes the DST Type 1 on the provided buffer, in-place. Uses the provided scratch buffer as scratch space.

pub fn process_dst1(&self, buffer: &mut [T])

Computes the DST Type 1 on the provided buffer, in-place.
