Graph of ultrametric type matrices

WebA general ultrametric matrix is then the sum of a nonnegative diagonal matrix and a special ultrametric matrix, with certain conditions fulfilled. The rank of a special ultrametric matrix is also recognized and it is shown that its Moore--Penrose inverse is a generalized diagonally dominant M -matrix. WebThe phylogramR package is a tool for for developing phylogenetic trees as deeply-nested lists known as “dendrogram” objects. It provides functions for conversion between dendrograms and “phylo” class objects, as well as several tools for command-line tree manipulation and import/export via Newick parenthetic text.
