Is there any integrator using variable-step, such as Rosenbrock, for stiff 
problems
y' = f(x,y) ?

ODE's are solved in (my) Octave (I have the latest Cygwin Windows binaries, 
2.1.31) by the
LSODE routine and the independent variable values have to be given by the 
user, so one has
to know a priori the behaviour of the solution.
