$LU$ decomposition method for solving fuzzy system of linear equations. (English) Zbl 1088.65023
Summary: The LU decomposition method is considered, for solving fuzzy systems of linear equations. We consider the method in the spatial case when the coefficient matrix is symmetric positive definite. The method is discussed in detail and followed by the convergence theorem and illustrated by solving some numerical examples.
