Periodic boundary conditions

I'm solving a system of coupled differential equations on a linear mesh with periodic boundary conditions imposed to join the ends.
I am having two problems.
1. I want to define a random spatial distribution as initial condition.
2. I want to apply periodic boundary conditions.
But I am not able to match the two aims.
I try using the MATLAB rand() function to generate randomness, but I am unaware of how to couple this in a functional form with x to lead to a random distribution over the mesh points. After generation of the random distribution I need to ensure the end points match.
Could anyone help me. I am a beginner with COMSOL
Thanks for your help
