isNodeFixed

Check if node is fixed

Since R2022a

Syntax

isFixed = isNodeFixed(graph,nodeID)

Description

isFixed = isNodeFixed(graph,nodeID) returns a logical flag indicating whether the node with the specified nodeID in the factor graph, graph is fixed or not fixed during optimization.

Input Arguments

graph — Factor graph

factorGraph object

Factor graph, specified as a factorGraph object.

nodeID — Node ID of existing node

nonnegative integer

Node ID of an existing node, specified as a nonnegative integer.

Output Arguments

isFixed — Fix status of node

true or 1 | false or 0

Fix status of the node, returned as a logical 1 (true) or 0 (false). The function returns true when the node is fixed, and returns false when the node is free.
