can i input the event based with a mean of 10^-3(exponential distributed) to matlab code function block

function y = repairTimeFcn(u)

repairTime = random('exp',0.1);

y = u + repairTime;

end

and then input it to single server block

Hi Mai,

Yes, you can use the provided MATLAB code to generate repair times with an exponential distribution and a mean of 0.1. The random('exp',0.1) function in MATLAB generates random numbers from an exponential distribution with a mean of 0.1.

Here's an example of how you can use this code in a MATLAB Simulink model:

• Create a MATLAB function block in your Simulink model.
• Open the block's dialog and enter the following code in the "MATLAB Function" field:

function y = repairTimeFcn(u)
    repairTime = random('exp', 0.1);
    y = u + repairTime;
end

• Connect the input u to the MATLAB function block and connect the output y to the single server block.

This MATLAB function block will take the input u (which represents the event-based random number) and generate a repair time based on an exponential distribution with a mean of 0.1. The repair time is then added to the input u, and the resulting value is passed to the single server block
