Details:

In version 3.0.0 of the control package, the function impulse is returning
different results for different time vectors passed as arguments, but it
should not:


octave:1> pkg load control
octave:2> s = tf (1, [1 1]);
octave:3> y = impulse (s, 0 : 0.01 : 1);
octave:4> y (1)
ans =  0.10000
octave:5> y = impulse (s, 0 : 0.1 : 1);
octave:6> y (1)
ans =  1


Notice that the later value is correct, but the former is not.
