How to run a simulation with an input array?

Hello Guys,

I have a model with 14 inputs whose values are in an excel sheet. I was able to read the values into a .m file but each input has 11 values (stores as an array). I have to feed the inputs to the model one by one i.e. for simulation1 I need to run the first value in the array of all inputs and then the 2nd value of all the inputs and then run the simulation/store the results. Any help would be appreciated. Thanks in ADV.

Use this block in your model. You can create a for loop in a script that iterates over your vector and assigns the value of the vector to the parameter of the block

mdl = 'mymdl'; % name of your model

x = rand(14 , 1); % this represents your data

for i = 1:numel(x)
  set_param([mdl '/Constant'] , 'Value' , num2str(x(i))); % set the value of the constant block
  simout = sim(mdl);                                      % simulate the model
  % do stuff
end
