Can i code nonlinear system simulation in matlab ?

Hello everybody
i am trying to simulate a non linear system that work proper in simulink with matlab code.
system shows in picture below:
i have a system that get input for state space and the outputs are two variables(Displacement and Velocity) .this two variable are inputs of fuzzy inference system and outputs this system is input of state space in next step time.
can i code this system with m files' matlab without simulink ?

Divide the work in smaller bits and work on them one at a time. Feel free to ask questions here if you get stuck.
If you meant to ask if one can automagically transform a Simulink model into Matlab code then no.
If you want someone to do your job, then you are probably in the wrong place.
No i want do by myself
I know , i can use ss() function for create a state space system . But each time input matrice will change and i dont know how can i change it each time
Hi Saeed,
I am interested in your post as I am currently facing the same issue.
Ithink that if will be helpful if you check on the use of feedback in between 2 systems, in which essentially treating the controiler as a state space system as well. The link is provided as: https://www.mathworks.com/help/control/ref/feedback.html
Could you please share your method if you happened to solve it? Much appreciate.
