I want to pick a number from a set of number, i.e [1011, 1001, 1111, 1101, 0011] once at the beginning of each simulation. But i am not getting any help from the random number generator blocks. MATLAB code works in this case, so I've used matlab fuction block to run the code in simulation. But the code keeps running and generating value. Is there any fix to this?
The code I'm using in the fuction block is:
function data = y
numbers = [1011, 1001, 1111, 1101, 0011, 0101, 1100];
% Generate a random index
index = randi(length(numbers));
% Display the random number

The MATLAB Function block is like any other blocks. It will execute at every simulaiton step.
The best way is to put this MATLAB Function block inside the Initialize Subsystem.
