writing transfer functions in matlab

Hi, I want to write a transfer function in matlab. I know we usually write in the following way
trans = tf([1 0 0], [1 0 1]);
This gives something as a function of 's'.
what if i wanted to write an equation that was a function of 's+x', where x is a constant. So instead of H(s), i want to write a function and evaluate at values of say H(s+5).
thanks

Write a MATLAB program to determine the partial fraction expansion of a rational z-transform. Using this program
determine the partial-fraction expansion of G(z).

The documentation has good examples on how to write transfer functions:

Do you want to see the resulting expression as a function of (s+x), or do you just want to write an equation as function of (s+x)? If it is the latter you could do this:
>> arg=tf('s')+5
arg =
s + 5
Continuous-time transfer function.
>> h=1/(arg+3)
h =
1
-----
s + 8
Continuous-time transfer function.
>> arg=tf('s')+10
arg =
s + 10
Continuous-time transfer function.
>> h=1/(arg+3)
h =
1
------
s + 13
Continuous-time transfer function.
