topoorder (biograph) - Perform topological sort of directed acyclic graph extracted from biograph object

Syntax

order = topoorder(BGObj)

Arguments

BGObj

Biograph object created by biograph (object constructor).

Description

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

order = topoorder(BGObj) returns an index vector with the order of the nodes sorted topologically. In topological order, an edge can exist between a source node u and a destination node v, if and only if u appears before v in the vector order. BGObj is a biograph object from which an N-by-N adjacency matrix is extracted and represents a directed acyclic graph (DAG). In the N-by-N sparse matrix, all nonzero entries indicate the presence of an edge.
