沿主对角线双向收缩法解分块带状矩阵方程组

摘要

给出了一种沿对角线双向收缩法解系数矩阵为严格块对角占优矩阵的线性方程组,这种算法与经典的LU分解算法进行了比较,例子说明了算法的有效性.%In this paper, biforward berrevent algorithm along the diagonal for block linear equation which coefficient is diagonal block strictly diagonally dominant matrix was given . this algorithm and the classic LU decomposition algorithm equire about the same amount of work. some numerical examples are presented to verify the efficiency of the algorithm.
