[Octave-bug-tracker] [bug #56560] Error by addition of two frd objects (control package)

[Doug Stewart]

Follow-up Comment #7, bug #56560 (project octave):

OK in __sys_group__.m
try adding 2 lines to make it look like this:


  if (! isa (sys1, "frd"))
    sys1 = frd (sys1, sys2.w);
        sys1.lti=sys2.lti;
  endif

  if (! isa (sys2, "frd"))
    sys2 = frd (sys2, sys1.w);
        sys2.lti=sys1.lti;
  endif

Let me know if this helps.
