A GUI to Set Simulink Model Parameters
This example illustrates how to create a GUI that sets the parameters of a
Simulink model. In addition, the GUI can run the simulation and plot the
results. The following picture shows the GUI after running three simulations
with different values for controller gains.
Techniques Used in This Example
This example illustrates a number of GUI building techniques:
•Opening and setting parameters on a Simulink model from a GUI.
•Implementing sliders that operate in conjunction with text boxes, which
display the current value as well as accepting user input.
•Enabling and disabling controls, depending on the state of the GUI.
•Managing a variety of global data using the
handles structure.
•Directing graphics output to figures with hidden handles.
•Adding a help button that displays
.html files in the MATLAB Help
browser.
