摘要
By combining the preconditioner I + S-a by Li et al. (Appl Numer Math 134:105- 121, 2018) and some elements of the last row of the majorization matrix associated with the coefficient tensor, we propose a new preconditioner and present the corresponding preconditioned Gauss-Seidel method for solving multi-linear systems with M-tensors. Theoretically, we give the convergence and comparison theorems of the proposed preconditioned Gauss-Seidel method. Numerical examples are given to show our theoretical results and the efficiency of the proposed preconditioner.
