预条件P(下标 C)=(I+C)后SSOR迭代法收敛性的加速

Aim It is aimed at accelerating the convergence of the SSOR iterative method. Methods It is proved by using matrix iterative analysis and comparison theorems. Results It concludes that accelerate the SSOR method when the matrix is a strictly diagonally dominant L-matrix. Conclusion The result that will help to solve the linear system of differential equation and limited element method.
