Class: Simulink.sdi.Run
Package: Simulink.sdi

Return signal ID at array index


signalID = runObj.getSignalIDByIndex(index)


signalID = runObj.getSignalIDByIndex(index) returns the signal ID for the signal at the specified index to the array of signals contained in the Simulink.sdi.Run object, runObj.

Input Arguments


Number specifying the index to the array of signals contained in a Simulink.sdi.Run object. The first index in the array is 1.

Output Arguments


Signal ID, a unique number identifying a signal in a run.


The Simulink.sdi.Run method, getSignalIDByIndex, returns the signal ID corresponding to a signal in a run. With the signal ID you can get the signal object representing the signal data and metadata. You can compare two signals by passing their signal IDs to Simulink.sdi.compareSignals.

% Configure model "slexAircraftExample" for logging and simulate
simOut = sim('slexAircraftExample','SaveOutput','on', ...
             'SaveFormat','StructureWithTime', ...
% Create a Simulation Data Inspector run
runID = Simulink.sdi.createRun('My Run','base',{'simOut'});
% Get the Simulink.sdi.Run object corresponding to the new run ID
runObj = Simulink.sdi.getRun(runID);
% Get the number of signals in the run
numSignals = runObj.signalCount;
% Get the signal ID for the first signal in the run
if numSignals > 0
   signalID = runObj.getSignalIDByIndex(1);
