Implicit Runge-Kutta method of fifth order with three stages (Radau IIA) for problems of the form My’=f(x,y) with possibly singular matrix M; with dense output (collocation solution).

Applicable for stiff problems of low to medium accuracy.

Applicable solver settings:

• Absolute tolerance
• Relative tolerance
• Initial step size
• Max step size
• Min step size
• Refine
• Limit data points to last
• Max Newton iterations
• F Newt
• Thet
