Regarding Transfer function blcok

I am working on a Simulink model Which consists of Various Simulink blocks. I have to replace all these blocks with Matlab Function by writing the equivalent Matlab Code in it.
I have got a problem while replacing the Transfer Function in it. i.e, I used "tf" command to replace the first order Transfer Function but my Matlab doesn't consist "Control_Toolbox" which is very expensive. So, Can I replace this Transfer Function with any other logic insted of using Control_ToolBox. The Transfer Function looks as shown below.
Your ideas can be really helpful. Thank you

Hi Nagasai,
When you can say logic, it refers to include types of blocks such as AND / OR / NOT etc instead of your trasnfer function... That´s why I said that it is not possible to do it in that way.
From the screenshot you attach, I think that you want to implement it in time-domain instead of in frequency domain. In this case, you could use the command
sys_ss = ss(sys)
where ss is your trasnfer function.
This function is part of the Control System Toolbox, for more details check this link:
Best,
Jesús

Hi Nagasai,
A transfer function relates the process output ith its input, usually written in frequency domain, where the analysis of such a systems is made by using Laplace transform. In this way, the amplitud of the output at certain frequency is described as a function of the frequency of the input signal. There is not relationship between a transfer function and a logic implementation, therefore, it cannot be replaced with any logic.
Best,
Jesús
