摘要
Abstract
For the coefficient matrix A being //-matrix of linear equations, the preconditioning matrix I+Wp was introduced. Through the elementary row transformation of the coefficient matrix, a new preconditioned Gauss-Seidel method was proposed to solve the linear equations. If A is an //-matrix, then (I+Wp)A is also an //-matrix. The convergence theorem was also obtained. It theoretically proved that the new preconditioned Gauss-Seidel iterative method converges faster than the classic Gauss-Seidel iteration method. Numerical example showed the validity of the new precondition Gauss-Seidel iteration method.关键词
