Auto scale absolute tolerance

Description

Allow the solver to dynamically adjust the absolute tolerance value for each state.

Settings

Default: On

On

Allow the solver to adjust the absolute tolerance

Off

Keep the absolute tolerance value fixed.

Dependencies

This option is visible when the following conditions are satisfied:

• Solver Type is set to Variable-step.

• Solver is not set to discrete (no continuous states).

If the Absolute Tolerance is set to auto, the AutoScaleAbsTol parameter is turned on by default and cannot be disabled. To disable this parameter, you must first specify a finite non-negative value for abstol.
