hasNode
Description
Examples
Check if Node Exists in Factor Graph
Create a factor graph and add a GPS factor to the factor graph connected to node 0.
fg = factorGraph; id = 0
id = 0
gps = factorGPS(id); addFactor(fg,gps);
Check if the factor graph contains node 0.
hasNode(fg,id)
ans = logical
1
Input Arguments
fg
— 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.
Extended Capabilities
C/C++ Code Generation
Generate C and C++ code using MATLAB® Coder™.
When generating portable C code with a C++ compiler, you must specify hierarchical
packing with non-minimal headers. For more information on packaging options, see the
packNGo
(MATLAB Coder) function.
