# Singular fuzzy linear systems

M. Nikuie

Abstract:

The linear system of equations $$A\tilde{x}=\tilde{b}$$ where $$A$$ is a $${n\times n}$$ singular crisp matrix and the right-hand side is a fuzzy number vector is called a singular fuzzy linear system of equations. Drazin inverse is one of the generalized inverses. In this paper the effect of Drazin inverse in solving such systems using $$LU$$ factorization is investigated. Here the computing Drazin inverse and solving singular fuzzy linear systems using MATLAB software are illustrated. stronger.
