clean up and vectorize code for dense output in ode45 * scripts/ode/private/ode_rk_interpolate.m: new file * scripts/ode/private/ode_rk_interpolate.m(hermite_quartic_interpolation): move to internal function, use vectorization and broadcasting. * scripts/ode/private/hermite_quartic_interpolation.m: remove file * scripts/ode/module.mk: list added and removed files * scripts/ode/private/integrate_adaptive.m: use new interpolation code.
