一种求解线性方程组的方法

A Method for Solving Linear Equction Systems

本文提出一种求解线性方程组的方法.当系数阵和自由项阵扰动后,求新未知数时,不必重复计算系数阵的逆阵,只要利用首次运算结果,加以适当变换,建立起新的公式,据此就可求出扰动后的未知数.

A method to solve linear equation systems is presented is presented.When the coefficient matrix and matrix of constant terms are perturbed,and the new unknowns are solved,it is unnecessary to compute repeatedly the inverse of the coefficient matrix.And only an appropriate transformation of the coefficients ts required which are besed upon first operationed results, and the new formula is established.The new unknowns after distribution therby will be found out.
