Struct fourier_algorithms::Autosort

pub struct Autosort<T, Twiddles, Work> { /* fields omitted */ }

Implements a mixed-radix Stockham autosort algorithm for multiples of 2 and 3.

Implementations

impl<T, Twiddles, Work> Autosort<T, Twiddles, Work>

pub fn counts(&self) -> [usize; 5]

Return the radix counts.

pub unsafe fn new_from_parts(
    size: usize,
    counts: [usize; 5],
    forward_twiddles: Twiddles,
    inverse_twiddles: Twiddles,
    work: Work
) -> Self

Create a new transform generator from parts. Twiddles factors and work must be the correct size.

impl<T, Twiddles: AsRef<[Complex<T>]>, Work: AsRef<[Complex<T>]>> Autosort<T, Twiddles, Work>

pub fn twiddles(&self) -> (&[Complex<T>], &[Complex<T>])

Return the forward and inverse twiddle factors.

pub fn work_size(&self) -> usize

Return the work buffer size.

impl<T: FftFloat, Twiddles: Default + Extend<Complex<T>>, Work: Default + Extend<Complex<T>>> Autosort<T, Twiddles, Work>

pub fn new(size: usize) -> Option<Self>

Create a new Stockham autosort generator. Returns None if the transform size cannot be performed.
