Parameter Tuning with MATLAB

Tunable block and global parameter updating, parameter sweeps, extreme value tests

Query and modify tunable block and global parameters with MATLAB^® in your real-time application as it is running. Perform parameter sweeps and extreme value tests.

Topics

Background

Tunable Block Parameters and Tunable Global Parameters
Changing tunable block parameters and tunable global parameters during real-time execution.

Parameter Tuning

Tune Parameters by Using MATLAB Language
Change block parameters while your real-time application is running on the target computer.
Tune Inlined Parameters by Using MATLAB Language
Tune inlined parameters that have been made tunable with MATLAB variables.
Tune Parameter Structures by Using MATLAB Language
Organize related parameters into a structure and use the structure to tune parameters.
Save and Reload Parameters by Using the MATLAB Language
Save real-time application parameter values to a file on the target computer.

MATLAB Interface

Target and Application Objects
Use the MATLAB Command Window to change properties and control the target computer and your real-time application.
Instrumentation Apps for Real-Time Applications
Interface with your real-time application by using instrument panel apps.

Limitations

Troubleshoot Parameters Not Accessible by Name
Investigate issues that prevent you from observing or tuning some parameters in the real-time application.
Troubleshoot Instance-Specific Parameters Not Saved
Investigate issues that prevent saving instance-specific parameters and parameters with custom storage classes to a MAT file.
Internationalization Issues
Learn about Simulink^® Real-Time™ support for internationalization.
