Representations And Properties Of The DMP Inverse For The Matrices

DMP inverse matrix is combined with previous studies of moore-penrose inverse and Drazin inverse to generate a kind of generalized inverse,DMP inverse of the matrix have some properties of moore-penrose inverse and Drazin inverse and have their own special properties.This article mainly study the solution of the DMP inverse of the matrix conditions and study their properties.The thesis is divided into three chapters:In chapter 1, we briefly introduce the research background of generalized inverse and some basic definitions and symbols.In chapter 2, we introduce the morphology of DMP inverse and its basic properties.In chapter 3, we study the solution and the expression form of DMP inverse of a class of special matrix and study the sum of these matrices.
