摘要
本文证明了由矩阵A的 (1,4 ) -逆A(1,4) 构成的线性算子A(1,4) A为正交投影算子 ,并将其应用到线性方程组极小最小二乘解问题中 ,从而获得极小最小二乘解的正交投影几何原理。
This paper proves that the linear operator A (1,4) A formed by (1,4)-inverse A (1,4) of Matrix A is the orthogonal projection operator. Its application in the maximum quadratic of linear equations can obtain the geometrical principle of the maximum quadratic orthogonal projection.
