Struct SimpleRealFFT 

pub struct SimpleRealFFT<T: Float> { /* private fields */ }

A wrapper for complex FFT to handle real data

Implementations

impl<T: Float + FromPrimitive> SimpleRealFFT<T>

pub fn new(size: usize) -> Self

Create a new real FFT with the specified size

pub fn resize(&mut self, size: usize)

Resize the FFT to handle a different size

pub fn fft(&mut self, time: &[T], freq: &mut [Complex<T>])

Perform a forward FFT on real data

pub fn fft_split(&self, in_r: &[T], out_r: &mut [T], out_i: &mut [T])

Perform a forward FFT on real data with split output

pub fn ifft(&mut self, freq: &[Complex<T>], time: &mut [T])

Perform an inverse FFT to real data

pub fn ifft_split(&self, in_r: &[T], in_i: &[T], out_r: &mut [T])

Perform an inverse FFT from split complex to real data
