This volume offers a gradual exposition to matrix theory as a subject of linear algebra. It presents both the theoretical results in generalized matrix inverses and the applications. The book is as self-contained as possible, assuming no prior knowledge of matrix theory and linear algebra.

The book first addresses the basic definitions and concepts of an arbitrary generalized matrix inverse with special reference to the calculation of {i,j,...,k} inverse and the Moore-Penrose inverse. Then, the results of LDL* decomposition of the full rank polynomial matrix are introduced, along with numerical examples. Methods for calculating the Moore-Penrose's inverse of rational matrix are presented, which are based on LDL* and QDR decompositions of the matrix. A method for calculating the A(2)T;S inverse using LDL* decomposition using methods is derived as well as the symbolic calculation of A(2)T;S inverses using QDR factorization.

The text then offers several ways on how the introduced theoretical concepts can be applied in restoring blurred images and linear regression methods, along with the well-known application in linear systems. The book also explains how the computation of generalized inverses of matrices with constant values is performed. It covers several methods, such as methods based on full-rank factorization, Leverrier-Faddeev method, method of Zhukovski, and variations of the partitioning method.

Reviews

"This book explores the computation of various kinds of generalized inverses of constant matrices, matrix polynomials, and rational functions, from the point of view of symbolic computation. The matter of stability is not considered.
After setting basic definitions and properties in Chapter 1, in Chapter 2 the author reviews various methods for constructing generalized inverses of constant matrices.

In the third chapter, techniques based on classical matrix factorizations are applied to "polynomial and rational matrices", i.e., matrix polynomials and rational matrix functions.

The discussion focuses mainly on theoretical properties and algorithms, rather than on the role of generalized inverses in solving particular problems, e.g., least squares problems. Some applications are briefly described in the last chapter.
Many examples involving matrices of small size are given, in order to illustrate the peculiarities of the algorithms. The implementation of some of the methods described is reported in the form of Mathematica programs. Due to the size of the font used, it is not always easy to read the program listings. It would have been preferable to attach to the volume a CD containing the code.

The English language used in the book is sometimes convoluted or incorrect, but on average it is rather comprehensible."
