矩阵的广义逆与正交投影(英文)

GENERALIZED INVERSE OF MATRIX AND ORTHOGONAL PROJECTION

讨论了矩阵的广义逆在正交投影中的应用 ,给出了一个向量在仿射空间S ={x∈Rn|Ax =b}的投影表达式 .

The applications of generalized inverse of matrix in orthogonal projection is discussed in this paper. The projection of a vector onto an affine space S={x∈R n|Ax=b} is given by an explicit formula.
