# Index Matrices: Towards an Augmented Matrix Calculus

**"Index Matrices: Towards an Augmented Matrix Calculus"** (ISBN 978-3-319-10945-9) is a monograph by Krassimir Atanassov, published in 2014 in the Springer series "Studies in Computational Intelligence", Vol. 573. This is the first monograph that presents the very concept of an index matrix and its related augmented matrix calculus in a comprehensive form.

It mostly illustrates the exposition with examples related to the generalized nets and intuitionistic fuzzy sets which are examples of an extremely wide array of possible application areas. The present book contains the basic results of the author over index matrices and some of its open problems with the aim to stimulating more researchers to start working in this area.
