Compute pairwise distance matrix

Compute pairwise distance matrix

Usage

compute_distance_matrix(
  left_mat,
  right_mat,
  distance = "euclidean",
  sigma = NULL
)

Arguments

left_mat

Numeric matrix of left units (rows = units, cols = variables).

right_mat

Numeric matrix of right units (rows = units, cols = variables).

distance

Character string specifying distance metric, or a function.

sigma

Optional covariance matrix for Mahalanobis distance. If NULL (default), the pooled covariance is estimated from data.

Value

Numeric matrix of pairwise distances (n_left x n_right).
