Matlab script declaring Simulink model variables

Question

I was given the following protected Simulink model:

It works manually (I click on "Run" on the Simulink GUI and it gives me the three outputs). I am writing a script using the Matlab SIMSET tool to define the necessary variables and to call this model in order to run it:

Constant=43;
Constant1=43;
Constant2=43;
Constant7=43;
Constant10=43;
Constant11=43;

t_stop = 100;
T_s = t_stop/1000;
options = simset('solver', 'ode5', 'fixedstep', T_s);
sim('test_lau.slx',t_stop,options)

I know that the interfaces "EC" and "UL" each take for input a vector, but even if I define two vectors in my script, how do I assign them to "EC" and "UL"?

Thank you in advance for your help!
