This paper intruduces the memory method for nonzero elements in the factor matrix of finite element equation system and two kinds of effective iterative method, SOR method and J-CG method, and presents the some algorithms applied to the program dessign. The presented algorithms are applied to the finite element solution to Possion equation.
