How to run Simulink with all possible permutations of variables

Hi all, I am trying to run my Simulink model that includes several variables. I want to know how to run it so that my model runs all possible permutations instead of me manually entering or changing the variable data each time. Thanks!

I have tried defining this data in matlab and then setting the constants as each variable name. I have also tried using simin from workspace to import the data stored in matlab. Neither of these options have worked. I keep getting errors regarding the dimension of my data.

Where are these variables used in your Simulink model?

If they are simple parameters, e.g., the value of a Gain block, you should be able to do something fairly simple like:

kVals = 1:10;
for k = 1:numel(kVals)
  simout(k) = sim('modelName','FastRestart','on');
end

If they are inputs to the model, then it depends on how your model is set up and may require something more complex.

All the variables are inputs to my model. Most of them are used in function blocks in my model as well. These variables include temperature, flow rate, and storage pressure. I wanted to set up my model so that it would run all combinations of

Pressure A,B,C

temperature A,B,C, D

flow rate A,B,C.

with each other to see how to changed my output.
