The Weighted Generalized Inverses of Block Matrices in Banachiewicz-Schur Form
NI Li-hu · Guizhou kexue · 2014
The conditions under which the weighted generalized inversesP(1,3M)and P(1,4N)can be expressed in Banachiewicz-Schur form are given in this paper. The existence of this form is proved by means of making a difference of the two formulas which is 0,as well as the necessary and sufficient conditions when these two are equal.
