R12 Release Notes

Known Software and Documentation Problems

This section updates the Fuzzy Logic Toolbox 2.1 documentation set, reflecting known Fuzzy Logic Toolbox 2.1 software and documentation problems.

ODE Solver Performance

Because most FIS contain Min, Max, and other blocks with zero-crossing detection, the default ODE solver can perform poorly in some cases. Two remedies are available:

• Choose a stiff solver. Several choices are available on the Solver page of the Simulation Parameters dialog box in Simulink.
• Disable zero crossing detection on the Advanced page of the Simulation Parameters dialog box
