Dear GSL,
I use gsl_odeiv_control to implement adaptive step size control.
I understand that this function reduces the step size by a scaling
factor to ensure that an error tolerance is met.
Is there any checking to be sure that underflow after many rescalings
does not cause the stepsize to become zero?
Is there anyway to ensure that the adaptive control never reduces the
stepsize below a prescribed lower bound regardless of the error?
Thank you.
