摘要
本文将求解不相容线性系统AX =b的极小范数最小二乘解问题转化为求解一类微分方程唯一解问题 ,然后利用微分方程数值方法构造了几个迭代格式 ,同时 。
The author transforms the least squares solution of the only key of one class differentiation equation,and then forms several interactive patterns by using differentiation equation value method.And these interactive patterns are also the point-wise interactive method in solving the extra inverse matrix A +.
