Used for dimensional checks. This does not convert values.
Radau chooses internal steps to meet error tolerances. The time step above controls recorded output. Use it for continuous differential equations with fast and slow dynamics; random, delay, step inputs, time-triggered branches and time-driven lookup tables are unsupported.
Smaller tolerances request more accuracy and may reach the work limit. Save Radau models as JSON; standard XMILE cannot represent this solver.
Use the same seed and settings to repeat a stochastic run.
