This paper has dealt with the multilevel preconditioning methods based on the recursi ve used of a 2*2 block incomplete factorization procedure in which the Schur complement is approximated by a coarse grid matrix. It has shown that how the successful development of a multgrid and hierarchical basis method prompted the introduction of equivalent algebric technique. Some numerical results of these methods with two problems will be examined.
