How to replace variable 's' in the transfer function with another variable

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?

[Adam]

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

[Joshua]

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)'?

Answer 1

[Andrei Bobrov]

yourTransferfunction = @(g)d(g+1);

[Joshua]

Could you please elaborate as I am unable to understand what your solution does.

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

[Fabio Gavilan]

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.
