Trait Implementations

impl<T> Direction for SseF64Butterfly15<T>

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 SseF64Butterfly15<T>

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

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

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.

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

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

fn get_inplace_scratch_len(&self) -> usize

Returns the size of the scratch buffer required by process_with_scratch

fn get_outofplace_scratch_len(&self) -> usize
