摘要

A new variant of NIF incomplete factorization method to solve three dimensional elliptical difference equations with nonsymmetrical coefficient matrices has been developed. Results are presented of testing the method numerically for convergence, the combined incomplete factorization method CIF interleaving NIF and HF methods at the same time changing the direction of calculation.
