Struct Convolution 

pub struct Convolution;

Direct and FFT-based convolution.

Implementations

impl Convolution

pub fn convolve_direct(signal: &[f32], kernel: &[f32]) -> Vec<f32>

Linear convolution via direct sum. O(N·M).

pub fn convolve(signal: &[f32], kernel: &[f32]) -> Vec<f32>

Linear convolution via FFT. O((N+M) log(N+M)).

pub fn correlate(a: &[f32], b: &[f32]) -> Vec<f32>

Correlation (not convolution): xcorr(a, b) with zero-lag at index len(a)-1.
