ReturnSimulink.sdi.Signal object by index


signalObj = runObj.getSignalByIndex(index)


signalObj = runObj.getSignalByIndex(index) returns the Simulink.sdi.Signal object, signalObj, at the index into the array of signals contained in the Simulink.sdi.Run object, runObj.

Get the Signal Object in a Run

The Simulink.sdi.Run method, getSignalByIndex, returns a signal object representing the signal data and information in a run. You can modify the signal object properties to configure the signal for plotting or comparing to other signals in the Simulation Data Inspector.

% Configure model "slexAircraftExample" for logging and simulate
simOut = sim('slexAircraftExample','SaveOutput','on',...
% 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 Simulink.sdi.Signal object for the first signal in the run
if numSignals > 0
   signalObj = runObj.getSignalByIndex(1);
