Transfer Matrix using "connect" function

Hello, I need to determine the transfer matrix for the following diagram via the "connect" function in 2 different ways (both using the connect function).

Does anyone know how can I do that?

Thank you!

You mean the transfer function of multiplying the input by 1/6 ?

Addition takes no time, so the feedback is instant. So we get

  u - 5*y = y     %steady state
  u = 6 * y
  y = u / 6

Yes, the transfer function.

U should be a column vector. I specifically need to do this via the connect function.

Using your reasoning, what should I write in the command line?

Thank you!

Do you mean https://www.mathworks.com/help/control/ref/connect.html ? "Block diagram interconnections of dynamic systems" ?

If so why would you care about doing it 2 different ways? And block diagram interconnect would not get you the transfer function.

One seldom talks about transfer functions for purely linear relationships: one would instead tend to talk about "gain". "transfer function" seems to be used only when talking about implicit laplace transforms and thus dealing with frequencies and derivatives.

I am a beginner to Matlab, and this is the first homework regarding it from University.

Yes, indeed, "Block diagram interconnections of dynamic systems" is the closest I found regarding my question. In this case "gain" would be more appropiate.

Using 2 methods, I suppoose using the Index-Based Interconnection and a Feedback Loop.

So is there a way of using the aforementioned "connect" fucntion?

Thank you!
