chebyshev acceleration technique for solving fuzzy linear system

in this paper, chebyshev acceleration technique is used to solve the fuzzy linear system (fls). this method is discussed in details and followed by summary of some other acceleration techniques. moreover, we show that in some situations that the methods such as jacobi, gausssidel, sor and conjugate gradient is divergent, our proposed method is applicable and the acquired results are illustrated by some numerical examples.
