How can i populate an array using a for loop?

I need to create a 1D array of n elements. The array needs to be populated with a different random number in each element using a for loop. So far, I have:

prompt = 'Enter a value for n:' ; n = input(prompt); for i = 1:n A(1,i) = rand end

It's not quite working right. Any tips?

You have just to pre-allocate before the loop

A=zeros(1,n)
