treenomial (version 1.1.4)

wedge: 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

# NOT RUN {
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)

# }
