I've now added functions gsl_odeiv2_evolve_apply_fixed_step and gsl_odeiv2_driver_apply_fixed_step for this purpose, available at Bazaar (bzr) development branch ode-initval2 at savannah. Download and compile with commands: bzr checkout http://bzr.savannah.gnu.org/r/gsl/ode-initval2/ cd ode-initval2 autoreconf -i -f; ./configure --enable-maintainer-mode ; make -- Tuomo.Keskitalo@iki.fi http://iki.fi/tuomo.keskitalo
