Since R2022a

Syntax

nodeExist = hasNode(graph,nodeID)

Description

nodeExist = hasNode(graph,nodeID) checks if a node with the specified ID nodeID exists in the factor graph graph.

Input Arguments

graph — Factor graph

factorGraph object

Factor graph, specified as a factorGraph object.

nodeID — ID of node to check

nonnegative integer

ID of node to check, specified as a nonnegative integer.

Output Arguments

nodeExist — Node exists in the factor graph

false or 0 | true or 1

Node exists in the factor graph, returned as a logical 0 (false) or 1 (true). The function returns 0 if the node does not exist, and 1 if it does exist.
