How do I input a (1+bS) block into simulink， when b is const.?

I am trying to solve a system.

I know how to input a block like (1/as+b), but a (aS+b) block. Could someone help me with how to input this block in simulink?

Here is a picture of the block diagram

Hi,

You can use MATLAB Function block in Simulink Library Browser to create custom functions. Double-clicking the MATLAB Function block opens the MATLAB Function Block Editor, where you write the MATLAB function.

You can use tf to create a transfer function in MATLAB.

Assume the value of b=2 , the below code snippet will create the transfer function 1+2s

>>num = [2 1];
>>den = [1];
>>tf(num,den);

Hope this helps.
