wedge: Performs the wedge operation

In treenomial: Comparison of Trees using a Tree Defining Polynomial

Performs the wedge operation

Description

Calculates the result from the wedge operation on two real coefficient matrices, two y evaluated polynomial coefficient vectors or two phylo objects.

Usage

wedge(A, B, type = c("default", "yEvaluated", "phylo"), y)

Arguments

A, B	two real coefficient matrices, complex coefficient vectors or phylo objects
type	one of: “real” tree distinguishing polynomials in two variables x (columns) and y (rows) “yEvaluated” tree distinguishing polynomials with y evaluated at a specified argument “tipLabel” complex coefficient polynomial that utilize binary trait tip labels on the phylo objects
y	the y value to evaluate the polynomial at when type is “yEvaluated”, ignored otherwise

Value

the wedge result in the same form as the arguments

Examples

library(treenomial)
library(ape)

# wedge two real coefficient matrices

leaf <- matrix(c(0,1), nrow = 1, ncol = 2)
wedge(leaf, leaf)

# wedge two complex coefficient vectors

leaf <- as.complex(c(0,1))
wedge(leaf, leaf, "yEvaluated",5)
