poisson equation with periodic boundary conditions using finite difference

Hello,
I want to solve Poisson's equation on a 2d, n*n, rectangle with
periodic b.c. How should I set up the matrix of coefficiets in finite
differene? Ku=b, K=[-2 1 0 0 ...0 0 1; 1 -2 1 000.....000 ; ......; 1
000....0000 1 -2 ] is singular, have 'n' zero eigen values. (Note: I
am only allowed to use finite difference, and boundary conditions are
PERIODIC).

Thank you,
Farshid
