plot.matching_result

Produces a histogram of pairwise distances from a matching result.

Solves optimal pairing and matching problems using linear assignment
algorithms. Provides implementations of the Hungarian method (Kuhn 1955)

matching plots, sites, samples, or any pairwise optimization problem.
Supports rectangular matrices, forbidden assignments, data frame inputs,
batch solving, k-best solutions, and pixel-level image morphing for
visualization. Includes automatic preprocessing with variable health
checks, multiple scaling methods (standardized, range, robust), greedy
matching algorithms, and comprehensive balance diagnostics for assessing
match quality using standardized differences and distribution comparisons.
