【摘要】 给出了求解大规模稀疏线性方程组的一个实用算法；该算法能够保持矩阵的稀疏性和减少存贮量，并且能够求解一些大规模的问题．而这些问题所对应的系数矩阵可能不是稀疏的．更多还原

【Abstract】 A algorithm for solving large-scale sparse group of linear equations is presented. This algorithm can keep the sparsity of matrix, decrease storage and solve some large-scale problems, while the matrix of corresponding coefficients of these problems may not be sparse.更多还原
