UnrootedTreesMatchingSplit: Number of trees consistent with split

Description

Calculates the number of unrooted bifurcating trees consistent with the specified multi-partition split, using the formula of Carter et al. (1990).

Usage

UnrootedTreesMatchingSplit(...)
LnUnrootedTreesMatchingSplit(...)
Log2UnrootedTreesMatchingSplit(...)

Arguments

…

A series or vector of integers listing the number of tips in each of a number of tree splits (e.g. bipartitions). For example, 3, 5 states that a character divides a set of eight tips into a group of three and a group of five.

Value

UnrootedTreesMatchingSplit() returns an integer specifying the number of unrooted bifurcating trees consistent with the specified split.
