    Open Live Script

    Open the model DiagnosticDemo.

    model = "DiagnosticDemo";
open_system(model);

    Create a sldiagviewer.DiagnosticReceiver object. This object receives the diagnostic details from all model operations until the object is deleted.

    rx1 = sldiagviewer.DiagnosticReceiver;

    Add a few sample warnings to the model by setting the StartFcn model callback.

    setWarningCmd = sprintf([
    'for i = 1:5\n', ...
        'sldiagviewer.reportWarning("Sample warning.");\n', ...
    'end']);
set_param(model,"StartFcn",setWarningCmd);

    Simulate the model.

    sim(model);
    Warning: Sample warning.

    Warning: Sample warning.

    Warning: Sample warning.

    Warning: Sample warning.

    Warning: Sample warning.

    Get the diagnostic details generated during model simulation by using the sldiagviewer.DiagnosticReceiver object rx1. 

    stage1 = getDiagnostics(rx1)
    stage1=1×5 cell array
    {1×1 MSLDiagnostic}    {1×1 MSLDiagnostic}    {1×1 MSLDiagnostic}    {1×1 MSLDiagnostic}    {1×1 MSLDiagnostic}

    Delete the DiagnosticReceiver object rx1.

    delete(rx1);
