Struct CrossCorrelation 

Source 
pub struct CrossCorrelation {
    pub values: Vec<f64>,
    pub max_lag: usize,
}
Expand description

Cross-correlation between two real-valued signals.

Computes R_xy(k) = Σ x[n] * y[n+k] for k in [-max_lag, max_lag].

Fields§

§values: Vec<f64>

Cross-correlation values; index 0 corresponds to lag -max_lag.

§max_lag: usize

Maximum lag in each direction.

Implementations§

Source§

impl CrossCorrelation

Source

pub fn compute(x: &[f64], y: &[f64], max_lag: usize) -> Self

Compute cross-correlation between x and y up to max_lag.

Both signals are mean-subtracted before computation.

Source

pub fn peak_lag(&self) -> i64

Return the lag at which cross-correlation is maximum.

Negative lags mean x leads y; positive lags mean y leads x.

Source

pub fn at_lag(&self, lag: i64) -> f64

Return the cross-correlation value at a given lag.
