[−][src]Function emd::distance_generic

pub fn distance_generic<D>(
    X: &ArrayView2<f64>, 
    Y: &ArrayView2<f64>, 
    distance: D
) -> f64 where
    D: Fn(&ArrayView1<f64>, &ArrayView1<f64>) -> f64, 

Computes the EMD with a desired cost function (i.e., distance).

Uses the Euclidean distance between rows (vectors) in a matrix as a cost function. Each matrix may represent for example a multivariate histogram.

Arguments

  • X - First matrix
  • Y - Second matrix
  • distance - Distance metric
