Determine if run ID is valid



valid = Simulink.sdi.isValidRunID(runID) returns 1 (true) if runID corresponds to a run in the Simulation Data Inspector repository.

This example shows how to check whether a run ID is valid. You can use Simulink.sdi.isValidRunID to ensure you have valid data throughout your script.

Create a Simulation Run

Simulate the model sldemo_fuelsys to create a run in the Simulation Data Inspector, and use Simulink.sdi.getAllRunIDs to get its run ID.

% Simulate model

% Get run ID
runIDs = Simulink.sdi.getAllRunIDs;
runID = runIDs(end);

Check Run ID Validity

Check to verify that the Simulation Data Inspector has a run corresponding to the run ID.

ans = logical

Delete the Run and Check Validity

You can delete runs to clear out memory space or clean up the Simulation Data Inspector UI. When you delete a run, the run ID for that run becomes invalid.


ans = logical

Input Arguments

collapse all

Unique Simulation Data Inspector run identifier, specified as a positive integer. The Simulation Data Inspector assigns run IDs when it creates runs. You can get the run ID for your run using Simulink.sdi.getAllRunIDs or Simulink.sdi.getRunIDByIndex.

Output Arguments

collapse all

Run validity indicator, specified as a numeric or logical 1 (true) or 0 (false). When valid is true, the runID is valid. When valid is false, the runID is invalid.
