基于倾向一侧的对称/反对称分裂(LHSS)迭代方法,提出了一类求解Jacobi矩阵在解x^*处为大型稀疏非埃尔米特矩阵的非线性方程组的Newton-PLHSS方法,给出了这类不精确牛顿法的两种局部收敛性定理。数值结果验证了该方法的正确性和有效性。
Based on the lopsided Hermitian/skew-Hermitian(LHSS) iteration methods,a class of Newton-PLHSS methods for solving large sparse systems of nonlinear equations with positive definite Jacobi matrices at the solution points is proposed.Two types of local convergence theorems of this class of inexact Newton methods are given.Numerical results confirm the correctness and effectiveness of the proposed methods.
