I already discretized pde by central difference method, but not sure how to create a code for iterative methods such as Jacobi and Gauss Seidel.

Sparse linear solvers are already available in Matlab, the backslash operator per default uses the Umfpack direct solver
y = A\x;

for iterative solvers you can for example use gmres or bicg
help gmres
help bicg
