How to simulate a model dynamically from m-file?

I am calling a model in a loop. but every time model is simulated. I want to simulate model once and change the input to the model dynamically during the simulation. How to do it.

for t=1:1:10
  Ax=ax(t);   Ay=ay(t);   Az=az(t);
  P=p(t);     Q=q(t);     R=r(t);
  PSI=psi(t); THETA=theta(t); PHI=phi(t);
  U=u(t);     V=v(t);     W=w(t);
  X=x(t);     Y=y(t);     Z=z(t);
  sim('NC_Manas'); 
end

Thanks in advance....

The "From Workspace" block will take arrays of the form [time value] and step through the values at the time step defined. See examples here:

If you need the MATLAB code to be run continuously and feed inputs to the model, you need to run it in one of the three MATLAB function blocks available, so it runs as part of the model.
