  • An Iterative Method Using Piecewise Valued Basic Vectors for Solving Linear Systems with Symmetric Coefficient Matrix

抄録

This paper presents an iterative method using piecewise valued basic vectors for solving linear systems with a symmetric coefficient matrix. The solution of linear systems is easily obtained by the proposed iterative method which repeats the following four operation. 1) Make the some independent systems in which total number of freedoms is reduced by Galerkin's method using the piecewise valued basic vectors. 2) Compute the approximate solution of these systems by other iterative method. 3) Obtain the best approximate solution of original linear systems by linking each approximate solution. 4) Update the proposed basic vectors by using the best approximation. Validity and efficiency of the proposed iterative method are studied and shown in several numerical examples.
