摘要
Schur补理论在科学计算和统计学中有着广泛应用,S-SOB矩阵是H-矩阵的一个子类,本文研究S-SOB矩阵的Schur补问题,证明了 S-SOB矩阵的Schur补在一定条件下是SDD矩阵,最后通过数值例子说明结果的正确性.
Abstract
Schur complement theory is an momentous research field with wide applications in scientific computing and statistics.S-SOB matrix is a subclass of H-matrix,and in this paper we study the Schur complement problem of the matrix and prove that it belongs to the SDD matrix class under certain condi-tions.Numerical examples illustrate the validity of the results.
