摘要
给出了解线性方程组Ax =b的一类新的预条件迭代法 ,并证明了其收敛性 .数值例子表明 。
A new type of preconditioned iterative methods for solving a linear system Ax=b are presented,some of related convergent results are proved.Some numerical examples illustrate that the convergence rate of the new preconditioned method proposed is superior to the classical Gauss-Seidel iterative methods.
