摘要/描述

In this paper, a class of best approximation problems of matrices under inequalityconstraints are firstly presented and studied. For real matrices, symmetric matrices andantisymmetric matrices respectively, we have given the conditions for the existence ofsolutions and expressions of general solutions. Furthermore, the best approximationsolutions and algorithms of them are provided.
