摘要
研究系数矩阵为箭形矩阵的线性方程组的求解问题.利用矩阵分解技术,结合箭形矩阵的结构特点,建立了箭形线性方程组的一类追赶法.经运算量分析表明,此方法的运算量是线性量级,数值算例说明该方法实际可行.
In this paper,the problem of solving the system of linear equations with arrowhead coefficient matrix is studied.By using the matrix decomposition technique and combining the structural characteristics of the arrowhead matrix,a class of chase-after method for the system of linear equations with arrowhead coefficient matrix is established.The calculation is shown to be linear.And the numerical example shows that the proposed method is practical.
