pub fn dtw(a: &[f64], b: &[f64]) -> (f64, Vec<(usize, usize)>)Expand description
Implementation of Dynamic Time Warping (DTW) algorithm. This function computes the DTW distance between two sequences and returns the distance along with the optimal path.
§Arguments
a- First sequence as a slice of f64 values.b- Second sequence as a slice of f64 values.
§Returns
A tuple containing the DTW distance (f64) and a vector of tuples representing the optimal path as pairs of indices (usize, usize).
§Examples
use fraug::quality_benchmarking::dtw;
let a = vec![1.0, 2.0, 3.0];
let b = vec![2.0, 3.0, 4.0];
let (distance, path) = dtw(&a, &b);
