Auto scale absolute tolerance


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


Default: On


Allow the solver to adjust the absolute tolerance


Keep the absolute tolerance value fixed.


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, specify a finite non-negative value for abstol.
