TreesMatchingSplit: Number of trees matching a bipartition split

Description

Calculates the number of unrooted bifurcated trees that are consistent with a bipartition split that divides taxa into groups of size A and B.

Usage

TreesMatchingSplit(A, B)
LnTreesMatchingSplit(A, B)
Log2TreesMatchingSplit(A, B)

Arguments

A, B

Integer specifying the number of taxa in each partition.

Value

TreesMatchingSplit() returns a numeric specifying the number of trees that are compatible with the given split.

LnTreesMatchingSplit() and Log2TreesMatchingSplit() give the natural and base-2 logarithms of this number.
