How to generate just one random number in every iteration of for loop?

I need to generate just one random number in every iterations.

    For i=1:10
      x(i)=rand(1)
      end
    %For example when i=4 (x(4)), this code generate 4 random x which is not my favorite i want just another random x

Your storing each random created in each loop, if you only want one just do

 x = rand (1);

I need to store them because these are the initial positions of a serie of particles. It is a part of code.

That's what you have in your original code.

At i=4 its generating the 4th random number and saving it in x(4). X(1:3) are already populated by the earlier loops.
