Trait Implementations

impl<T> Direction for Butterfly3<T>

pub fn fft_direction(&self) -> FftDirection

Returns FftDirection::Forward if this instance computes forward FFTs, or FftDirection::Inverse for inverse FFTs

impl<T: FftNum> Fft<T> for Butterfly3<T>

pub fn process_outofplace_with_scratch(
    &self,
    input: &mut [Complex<T>],
    output: &mut [Complex<T>],
    _scratch: &mut [Complex<T>]
)

Divides input and output into chunks of size self.len(), and computes a FFT on each chunk.

pub fn process_with_scratch(
    &self,
    buffer: &mut [Complex<T>],
    _scratch: &mut [Complex<T>]
)
