摘要
针对特殊结构的块状五对角大型线性代数方程组建立了一种线性插值求解方法,该方法所需要的乘除法运算量随着子方程的个数呈线性增长,而通常的Gauss消去法所需要的乘除法运算量随着子方程的个数呈立方增长。
To aim at special large-scale block linear algebraic equations of the five-diagonal matrix, a linear interpolation method is designed. Operational quantity of the method increases by linear when the subequations increase, but the Gauss expunction method inceases by cubic.
