[Dmitri A. Sergatskov]

Follow-up Comment #5, bug #63303 (project octave):

This particular case:


octave:1> function xdot = __f (x, t)
> xdot = [-x(2); x(1)];
> endfunction
octave:2> x0 = [1; 0];
octave:3> xdot0 = [0; 1];
octave:4> t = (0:1:10)';
octave:5> tol = 500 * lsode_options ("relative tolerance");
octave:6> x = lsode ("__f", x0, t);
