Signal Monitoring and Tracing with MATLAB

Signal visualization with and without real-time information

If you require only the signal value, not the time at which it reached that value, monitor the signal with MATLAB®. See Signal Monitoring Basics.

If you require the signal value and the time at which it reached that value, mark signals for logging with the Simulation Data Inspector or add a File Log to your model. See Signal Tracing Basics.

Parameter Tuning and Data Logging

Use real-time parameter tuning and data logging with Simulink® Real-Time™. After the example builds the model and downloads the real-time application, slrt_ex_param_tuning, to the target computer, the example executes multiple runs with the gain 'Gain1/Gain' changed (tuned) before each run. The gain sweeps from 0.1 to 0.7 in steps of 0.05.
