Parameter Tuning
Change the parameters in your Simulink model and observe the effect of those
changes during a simulation or while running an application in real time.
Simulink external mode — You use Simulink external mode to connect your
Simulink block diagram to your real-time application. The block diagram
becomes a graphical user interface (GUI) to that executable.
Simulink external mode allows you to change parameters by editing the block
diagram while running Simulink in external mode. New parameter values are
automatically transferred to the real-time application while it is running.
Changing parameters — There are different types of model parameters that
you can change while running your real-time application. For example,
parameters include the amplitude of a gain and the frequency of a sine wave.
After you connect your real-time application to your Simulink model, you can
change parameters. You can change these parameters before or while your
real-time application is running by using one of the following methods:
Block parameters — Change values in the dialog boxes associated with the
Simulink blocks.
Block parameters for masked subsystems — Change values in
user-created dialog boxes associated with a subsystem.
MATLAB variables — Create MATLAB variables that represent Simulink
block parameters, and then change parameter values by entering the
changes through the MATLAB command line.

page 3-49.
