In most cases assignin should be avoided for more effiicent ways of passing data between workspaces. The documentation states " Best Practice: Passing Arguments The most secure way to extend the scope of a function variable is to use function input and output arguments, which allow you to pass values of variables."
Numbered variables are a sign that you are doing something wrong.

You use x but you do not define it.

Using a random variable would result in a discontinuity, which fminunc() is not designed to handle.
Your question is not clear as to whether you want to use a random variable, or a value randomly selected from a list of potential values. If you want to select randomly from the variable named x then
random_x = x(randi(numel(x));
