Create a Run

This example creates a run in the Simulation Data Inspector by simulating a model that logs data.

out = sim('sldemo_autotrans');

Access Run and Signal Data

Access the run and signal data using the Simulation Data Inspector programmatic interface. Use the Simulink.sdi.getCurrentSimulationRun function to get the Run object created when you simulated the sldemo_autotrans model.

autoRun = Simulink.sdi.getCurrentSimulationRun('sldemo_autotrans');

Use the getAllSignals function to get an array of Signal objects containing the logged signal data.

autoSigs = getAllSignals(autoRun);

You can use a for loop to inspect or analyze the data in each Signal object in the array. For example, you could check the name of each signal.

count = length(autoSigs);
for idx = 1:count
    sig = autoSigs(idx);
    name = sig.Name;
    formatSpec = "The signal at index %d is named %s\n";
    fprintf(formatSpec,idx,name)
end

The signal at index 1 is named EngineRPM
The signal at index 2 is named Throttle
The signal at index 3 is named BrakeTorque
The signal at index 4 is named ShiftLogic:1
The signal at index 5 is named ImpellerTorque
The signal at index 6 is named OutputTorque
The signal at index 7 is named VehicleSpeed
The signal at index 8 is named TransmissionRPM
