I have these steps to simulate data
pd= makedist('normal')
x = rand(pd,30,1)
How can I repeat the data generation process?

Call the functions multiple times. For example you can put it into a for loop:
for k = 1 : 100
pd= makedist('normal')
x = rand(pd,30,1)
% Now do something with x.
end
but that's SO obvious that I don't think it answers your question because you must have already considered that trivial solution. Please explain better.

Yes, it is true. It will run your code 100 times.

Well, I do not see any point in initializing pd every time through the loop instead of just once before the loop.
I also do not understand why you do not just use randn()
