摘要
本文给出解超定线性方程组的一个新方法—直接修正法,并绐出最佳步长的选取方法。最后给出改善病态方程组的解的实例。
This paper gives out a new algorithm for solving overdetermined linear equations—a direct correction algorithm and a method of choosing the optimum step. Then, as an example, the solution to the ill conditioned system of equations is also presented.
