ZERO Pole Block cant change s term value

How can i use a zero-pole block to input

5/(0.2s+1)

I cant figure out how to give a value of 0.2 to the s term in the pole

hi

5/(0.2s+1) = 25/(s+5)

now you know !

Well, what are you trying to do ?

The two expressions above are equivalent. It may be easier to see in the second version that this tf has no zero and one pole at -5 rad/s.

So you can do for example :

[NUM,DEN] = zp2tf([],-5,1)
bode(NUM,DEN)

and actually see the roll off above the pole frequency.

Works grand .

Thanks.
