MATLAB: How to change default solver preferences for models in Simulink 6.5 (R2006b)

Question

I would like to change the default settings of the configuration parameters for Simulink.

Answer 1

The default settings for the Configuration Parameters can be changed as follows:

1. Go to File->Preferences->Simulink->Simulation in the MATLAB desktop

2. Click "Launch model explorer" button

3. In Model Explorer, select "Configuration preferences" on left pane.

4. In middle pane, select "Solver"

5. In the right pane, make any changes desired (such as Fixed Step solver)

6. Click Apply

7. Select "Configuration preferences" on the left pane a second time.

8. In the right pane, click "Save Preferences".

This causes your changes to be preserved through future MATLAB sessions.
