Consider a=1 and b=[1 2]; d=tf(a,b); how do we replace the 's' term in d with (g+1) or (g+1)/(g-2)? Is that even possible?

What 's' term? You have d, tf, g, a and b in your question.

The transfer function is d=s/((s+1)(s+2)). Can i replace the 's' with any other variable like 'g+1' or '(g+1)/(g+2)'?

This is known as an Anonymous Function. It is similar to lambdas from other programming like Python. Here is Wiki link if anyone wants to read into it further: https://en.wikipedia.org/wiki/Anonymous_function

If you fill in yourTransferfunction(1) you get:
"Error using indexing Subscript no. 2 is out of range."
This does not change the variable in the expected way.
