Re: run this in matlab for me

[Bhrigu Kansra]

I ran above code in MATLAB 2019a
The output was ( I've attached the output in pdf format too)

       -----------------------------------------------------------

z = tf('z',1)

z'          

tf(ss(z)')  

q=z +1

q'

tf(ss(q)')

q=z^3-2*z^2+3*z+7

q'

tf(ss(q)')

-----------------------------------------------------------

z =

 

  z

 

Sample time: 1 seconds

Discrete-time transfer function.

ans =

 

  1

  z

 

Sample time: 1 seconds

Discrete-time transfer function.

ans =

 

   z

Sample time: 1 seconds

Discrete-time transfer function.

  z + 1

 

Sample time: 1 seconds

Discrete-time transfer function.

ans =

 

  z + 1

    z

 

Sample time: 1 seconds

Discrete-time transfer function.

ans =

 

  z^2 + z + 2.892e-17

          z^2

 

Sample time: 1 seconds

Discrete-time transfer function.

q =

 

  z^3 - 2 z^2 + 3 z + 7

 

Sample time: 1 seconds

Discrete-time transfer function.

ans =

 

  7 z^3 + 3 z^2 - 2 z + 1

  -----------------------

            z^3

 

Sample time: 1 seconds

Discrete-time transfer function.

ans =

 

  7 z^4 + 3 z^3 - 2 z^2 + z + 2.425e-17
