Abstract: Using the elements of a nonnegative rectangular tensor A, classification discussion idea and some techniques of inequalities, the author gave an upper bound estimation of the largest singular value of A. The obtained results were verified by numerical examples. Numerical results show that the obtained estimation is more accurate than some existing results.

Key words: nonnegative tensor, singular value, upper bound, rectangular tensor
