[Help-gsl] Intermediate steps on gsl_odeiv_step_rk2

[Mafalda Sousa]

Hi,

I'm using this ODE solver and I wanted to know if there's a way of accessing
the intermediate steps for each gsl_odeiv_step_apply. For example, in the
case of using RK23 I would like to access to
s1=f(Tn,Yn)
s2=f(Tn+h/2,Yn+h/2*s1)
s3=f(Tn+3*h/4,Yn+3*h/4*s2)
s4=f(Tn+1,Yn+1)

but I only access s1 and s4.

Thanks in advance.

Mafalda
