I don't know if this is the expected behavior: `assert` correctly compares
struct fields values but skips type checking. E.g the followings structs


a.logical = true;
b.logical = false;
c.logical = 1;


are sometimes mistakenly considered equal


octave:11> assert (a, b)
error: ASSERT errors for:  assert (cond {i},expected {i},tol)

  Location  |  Observed  |  Expected  |  Reason
     ()           1            0         Abs err 1 exceeds tol 0 by 1
octave:12> assert (a, c)
octave:13> assert (a.logical, c.logical)
error: ASSERT errors for:  assert (a.logical,c.logical)

  Location  |  Observed  |  Expected  |  Reason
     ()           O            E         Class logical != double
