isspantree (biograph)

Determine if tree created from biograph object is spanning tree

Syntax

TF = isspantree(BGObj)

Arguments

BGObjBiograph object created by biograph (object constructor).

Description

TF = isspantree(BGObj) returns logical 1 (true) if the N-by-N adjacency matrix extracted from a biograph object, BGObj, is a spanning tree, and logical 0 (false) otherwise. A spanning tree must touch all the nodes and must be acyclic. The lower triangle of the N-by-N adjacency matrix represents an undirected graph, and all nonzero entries indicate the presence of an edge.
