Block Gaussian elimination methods for fuzzy matrix equations. (English) Zbl 1192.65034

Summary: The fuzzy matrix equation \(Ax = B\) is investigated by using the embedding approach. The conditions for the existence of the fuzzy solutions to the fuzzy matrix equation are discussed and three direct methods for solving model matrix equation are designed. Finally, some examples are given.
