Hello, I've a problem with the use of the tf function. Basically i try to build a tf function using ( s = tf('s') ) and then writing my function. It works only with few poles and zeros (it seems just a total of 4), but when i try to write a function with more poles and zeros, and then i try to run it, it just keeps running. Any solution to this problem?

Try clear everything and see if the problem persists.
clear all

I'm glad that the proposed solution works. Just keep in mind that you don't have to clear all every time. You can first check if there is another variable named 's' in the Workspace.
clear all
s = tf('s')
g = 100*(s+10)*(s-5)/(s*(s+8)*(s^2+s+1)*(s-5))
