线性方程组的不适定问题

摘要

有一类线性方程组是不适定的，为了求解不适定的线性方程组，给出相对最优特解的定义并且证明了相对最优特解的存在性、唯一性和稳定性.%There is a type of linear e quati on group which are ill-posed.In order to solve this type of linear equation group.This paper gives the defination of relatively optimal special solution and proves its existence,uniqueness and stability.
