Good; I hope it is useful to you.

I'm afraid I am unable to reproduce the crash. I installed control using `pkg install -forge control`, loaded it with `pkg load control`, and tried out the example functions found in `help tf`, and they worked.

>> s = tf ('s');
>> G = 1/(s+1)

Transfer function 'G' from input 'u1' to output ...

 y1:  -----
      s + 1

Continuous-time model.
>> num = {[1, 5, 7], [1]; [1, 7], [1, 5, 5]};
>> den = {[1, 5, 6], [1, 2]; [1, 8, 6], [1, 3, 2]};
>> sys = tf (num, den)

Transfer function 'sys' from input 'u1' to output ...

      s^2 + 5 s + 7
 y1:  -------------
      s^2 + 5 s + 6

          s + 7
 y2:  -------------
      s^2 + 8 s + 6

Transfer function 'sys' from input 'u2' to output ...

 y1:  -----
      s + 2

      s^2 + 5 s + 5
 y2:  -------------
      s^2 + 3 s + 2

Continuous-time model.

Though I did get a *ton* of compiler warnings when doing the `pkg install -forge control` step.

Could you provide more specific steps to reproduce the crash? What inputs are you using for "a" and "b" in "tf(a,b)"? And have you re-installed the `control` package since upgrading to Octave 4.4.0?

I've opened an issue on the Octave.app project if you want to track my progress on this: https://github.com/octave-app/octave-app-bundler/issues/37

It is really an important update. This is the first (DMG) version after 
Octave-4.0.3 that started-up successfully on my Macbook Pro 15 with macOS High 
Sierra 10.13.5. However, there are some (few so far) problems, for example, 
when I load control package and run function tf(a,b) the whole Octave crash and 
closed. Every time I try to run function (tf) it crashes.

Thank you

Hi, Octave Maintainers and Mac-interested Octave folks,

I have joined Sebastian Schoeps in putting together a Mac binary package of Octave. We 
have a "beta 2" release that is almost ready for prime time.

If you are interested, would you mind downloading and testing it out?


All beta releases will be available at: 

Source code used to produce this app bundle can be found at: 

Since this is an unsigned app, the first time you run it, you will need to right-click it 
and choose "Open" instead of just double-clicking it, so you get a dialog with 
the option to run it even though it's from an unidentified developer. We're looking at 
fixing this.
