i want to create a transfer function with num=[k*30] and den=[1 1 6 8] and k=1. But I need to change the value of k and it is automatically updated in the num. How can i do?

Create an anonymous function from the tf function call:
Example —
s = tf('s');
h = @(k) tf(k*30, [1 1 6 8]);
for k = 1:3
sys = h(k)
end
sys =
30
-------------------
s^3 + s^2 + 6 s + 8
Continuous-time transfer function.
sys =
60
-------------------
s^3 + s^2 + 6 s + 8
Continuous-time transfer function.
sys =
90
-------------------
s^3 + s^2 + 6 s + 8
Continuous-time transfer function.

One way is to construct symbolic transfer functions and manage them yourself, doing the calculations with laplace() and so on.
