Problem in writing MATLAB code of Simulink model (state space)

Hi, I want to write my simulink model into state space model.
Pictures of my simulink model are attached. What I tried so far (and isn't working) is:
dt=0.01;
t=0:dt:10;
for i=1:length(t)
x=A*x+B*u;
u=(G*ref-K*x);
x = cumtrapz(x);
% fun = @(x) x;
% x = integral(fun,0,Inf);
pause;
end
But its results are way different than that of simulink model. Kindly guide me how should I do it.

"I want to write my simulink model into state space model" - Your simulink model is pretty straightforward and already in standard form:
xdot=Ax+Bu
y=Cx+Du
You have your A,B & C matrices. D is zero in your case. There is no need to use the MATLAB function block to complicate things. Just use the Simulink State Space block. Feed in the matrices and you are done!!
