[math] resetting relative and absolute tolerances in ODE adaptive step size integrators

2011-04-12 Thread luc . maisonobe
Hi all, I have hit a limitation of the current implementation of ODE integrators with adaptive step size. For now, the tolerances that are used to adjust the step size are specified only at construction time and cannot be changed afterwards. However, these tolerances are highly problem-dependen
