Returns the number of eligible matches for the distance.

This will return a list of the number of finite entries in a distance matrix. If the distance has no subgroups, it will be a list of length 1. If the distance has subgroups (i.e. x is an BlockedInfinitySparseMatrix, it will be a named list.)

Usage

num_eligible_matches(x)

# S3 method for optmatch.dlist

# S3 method for BlockedInfinitySparseMatrix
num_eligible_matches(x)

Arguments

x

Any distance object.

Value

A list counting the number of eligible matches in the distance.
