isdag (biograph) - Test for cycles in biograph object

Syntax

isdag(BGObj)

Arguments

Description

Tip   For introductory information on graph theory functions, see Graph Theory Functions in the Bioinformatics Toolbox™ User's Guide.

isdag(BGObj) returns logical 1 (true) if an N-by-N adjacency matrix extracted from a biograph object, BGObj, is a directed acyclic graph (DAG) and logical 0 (false) otherwise. In the N-by-N sparse matrix, all nonzero entries indicate the presence of an edge.
