\title{
Adjacency matrix of the delaunay graph for BestMatches of Points
}
\description{
Calculates the adjacency matrix of the delaunay graph for BestMatches (BMs) in
tiled form if BestMatches are located on a toroid grid.}
\usage{Delaunay4Points(Points, IsToroid = TRUE,LC,PlotIt=FALSE,
Gabriel=FALSE)}
\arguments{
\item{Points}{[1:n,1:3] matrix containing the BMKey, X and Y coordinates of the
n,  BestMatches NEED NOT to be UNIQUE,  however, there is an edge in the Deaunay
between duplicate points!}
\item{IsToroid}{Optional, logical, indicating if BM's are on a toroid grid.
Default is True}
\item{LC}{Optional, A vector of length 2, containing the number of lines and columns of the Grid. Lines is a value slightly above the maximum of the x-coordinates and Columns is a value slightly above the maximum of the y-coordinates  of Points.}
\item{PlotIt}{Optional, bool, Plots the graph}
\item{Gabriel}{Optional, bool, default: FALSE, If TRUE: calculates the gabriel
graph instead of the delaunay graph}
}
\value{Delaunay[1:n,1:n] adjacency matrix of the Delaunay-Graph}
